Hi, I'd like to help you with your question.
From what you have described to me, it sounds like you were not compatible with this man and you did the right thing in ending the relationship. He was critical, and he did not support you or love you. If he is like this now, how would he be if you stayed with him and ended up marrying him?
The relationship sounded very one sided. You were supportive and loved him, but he asked for a chance to fall in love with you. However, I'm not sure how he would achieve this. There is no guarantee that he would feel the same as you did even after lots of time. It sounds like instead that he wanted a chance to keep manipulating you and continue to criticize you.
You have a lot reason to believe you will move on and find a new, and much healthier relationship. For one, you spotted the problems in this relationship and chose to end it. That is a very healthy response. It also means you see your relationships for how they are and when you feel they are hurting you, you get out. You gave this relationship a good chance to catch on, and when you saw that it was not going to, you chose a very healthy alternative. That is a lot more than most people can do.
Anytime something in your life comes to an end, whatever it may be, you are going to experience a time of grief and mourning. You loved this person and the loss of that love and the subsequent feelings that go with it can make you feel many difficult emotions. Here are the stages of grief:
1. Denial— You probably will not experience this stage since you were the one who ended the relationship.
4. Depression- it sounds like this is where you are now.
When people grieve, they can go through some stages, all of the stages or get stuck in one stage. Since you just ended this relationship, give yourself time to experience the grief. You may move from one stage to another and that is ok.
The length of time you experience grief varies from person to person. However, if you find that after a year you are still unable to move on from this relationship, considering counseling. Talk with your doctor for a referral or if you attend church, your pastor may be able to help.
