If you don't hear from him it's appropriate to follow up with him. After all, you've got an understanding to talk to another at least one time per week. Having "space" does not have to translate to avoidance or ignoring one another. Crowding is one thing and touches base another.
It is good to keep intentions clear and appropriate of you to ask for clarification. The two of you are not trying to get alienated. You can't let yourself get so anxious (it's not healthy for you). And, he may perceive your anxiety and adopt it as his own (mistakenly) and keep his distance as a result of it (thinking he's too stressed out to speak to you and not wanting to stir you up unnecessarily).
It's not wrong per se. It is a mental and emotional pattern that you've been using in the past. Society also hints that the man should be the pursuer. You need him to give you the best answer he can at this time. Even if he is still confused (most likely) he can still communicate this to you.
It may be helpful if possible to ask him to meet face to face at some point. Needing space as I've mentioned does not man alienation from one another. Even if you reach out first, it does not mean that he does not miss you or would miss you less if you step up and contact him. It would be cowardly if you contact him and he does not follow through. No matter what your actions are, his feelings belong to him (including the level of him missing you and wanting you). Sometimes when a person knows that the other one is waiting for them, they slack off and this may be what he's doing (because he's convinced that no matter what, you'd be there for him). Keeping you in limbo is not healthy and all you're asking him is what's the next step for the relationship?
It is ok. You were seeing one another for a couple of years. Even though he's having some difficulties now, it does not mean that he has to drop everything or everyone in his life.
The tarot would not be indicative tool of exactly what he is thinking (and energies don't dissipate and appear each day that are predominant in one's life at a given time).
Does his work involve a lot of travel? He may be saying that he's gotten to finish a trip earlier than expected? You may ask him to clarify if it is unclear. Your not doing anything bad asking him questions that are general.
If this is what you feel, it is all right to say it. Try not to feel offended or personalize it. Words are just words in some instances. His feelings are something he's shared with you and that should be what shows you his love for you. You could mention that you miss his company or give an example of something the two of you did i.e. I miss going to that restaurant. you,etc.
Another reading at this time would not be appropriate as the energy can't be stirred so often. It seems that the confusion is dissipating though if he's talking to you about moving out and hinting he's having difficulties "life sucks" Yet, this is only a phase. He is not going to be stuck in confusing forever.
You've been under a lot of stress. If that is not managed, even the smallest things can affect you stronger than usual.
You're making a connection b/w your mother's criticism and his rejection. That is not healthy. Remember that a large part is based on your interpretation instead of the actual intent of the person. In your mother's case, she may think that she's helpful by saying things like that and, not realizing how these affect you. In his case, he's trying not to overwhelm you with his own issues right now.
You're taking everything as though it is your fault and it is not. Each person makes their own decisions.
There are a lot of things you've touched upon. If it is unbearable to handle all of it on your own, speaking to your MD or a face to face counselor may be helpful. If your work has EAP (employee assistance) benefits, you may qualify for free counseling. You've got to manage your anxiety level so the anxiety does not consume your life. As your mind becomes calmer, your outlook can change and how you deal with things. Depending on whether or not you're open to anti anxiety medication, there are natural options as well such as GABA, L-trytophan, Lemon Balm, Passion Flower to name a few.
Most importantly, whatever tools you've used to manage stress i.e. exercise, meditation, prayer, talking to friends, etc. try to resort to these as much as possible.
Journaling and working on monitoring and managing what you allow yourself to think about and dwell on is going to be important.
Another reading to look at energies influencing the situation would be appropriate in July (maybe the second week or so) to give enough time for issues to get cleared up meanwhile. Otherwise, you'd get pretty much the same energies showing up before then.
Focus on the positive not your fears. You said he's asked you to "hang in there" until this rough patch is overcome. That is what you're doing. Meanwhile, it does not mean stay anxious or doubtful. It means, carry on with your day and activities/responsibilities, stay calm and try to do things that make you happy (that are enjoyable) taking care of yourself. Try to stay optimistic when you communicate w/ him, provide him the support he needs (after all, he left his wife) and you're the one person left now for him to speak with. Even if his calls are not daily or as frequent as you'd like. Just by being calm and hanging in there you're showing him that you trust his judgment (rather than doubt whether he'd come back or not)He had said to you that he loves you. That is what you'd have to stay focused on. Not your fears!
