Hello,
I would like to give you some insight into your questions, and how both of your charts work with each other.
As far as whether you two would be able to make things up, I get a sense that yes, you would. First off, your Mars in Leo makes a positive aspect to his Jupiter in Sagittarius. Whenever I see this between charts, even though the disagreements may seem tough, the Jupiter person (him) always forgives and wants to appease the Mars person (you). So, yes, he will forgive you for your outburst and temper. Mars in a chart is how we act and even how we express anger. Being you are a Mars in Leo, if you are feeling as though you are being neglected, or not appreciated, you are going to be hurt. This hurt comes out in an angry fashion and you may say or do things that later you wish you hadn't. What you have to remember also, is that we are in a Mercury Retrograde period. During this time, a lot of communication and things that are said, tend to be taken back, or wished they hadn't been uttered! Think of a retrograde as a chance to "do over" something. This can be fixed. The reason you may have fears that when he states things about "when people start arguing it is the end of the relationship..." is due to you having a Scorpio Sun, Mercury and Neptune in your chart. Especially being a Scorpio Sun, your biggest fear is someone abandoning you, or not meeting your needs. Another issue we have here is that your Mercury in Scorpio is right with his natal Neptune. Mercury is how one communicates, and Neptune tends to cause confusion. Being he is the Neptune person in this equation, he may not completely understand "why" you got upset, or he may not realize the extent of his actions are. You may say one thing, but, he may hear another! Also, your Mars is on his Uranus placement in this chart, and this can be seen as him feeling you get angry over things too easily or quickly. The good news with this placement though, is, the anger subsides quickly, and you would have the capacity to get things ironed out.
The reason you may feel he puts others in front of you is due to his Moon position. His Moon is in Pisces, which is typical of someone who would spread themselves a bit thin and try to be helpful to whomever needs him. The reason why he closes himself off when in a misunderstanding with you is due to the fact your Pluto is right on his Mercury. Pluto is about having the last word, being in control and having power. He feels that he doesn't have a good excuse or any palatable reasoning for letting you down. It is easier for him to just acquiesce and shut down. He is one who would also be slow to anger. His Mars is in Gemini in hard aspect to his Jupiter. This aspect usually shows someone who when angry uses their words and it seems to come out of nowhere. Thing is, with him, it would be over as quickly as it seemed to come on.
You will talk again, and, I don't feel this relationship is over, but, it seems as though you both need to understand each other better and what makes the other tick. With you, you need acknowledgement, and not to feel as though you are easily put on the back burner if he has someone who he feels he needs to rescue or "help". I get a sense that he doesn't realize how much this hurts your feelings. I feel that with his chart, he sees it as him doing the right thing, or being there for those in his life. In his mind the other day, he was trying in his mind to meet you half way but offering to call when they were finished. He wasn't seeing this from your perspective - you having just arrived back, having an illness etc. You having that Mars in Leo, I am wondering if you try to not complain too much or act like you "need" him. Sometimes with this Mars placement, you want to appear as though you are strong and can handle anything. He may have felt that this friend was much weaker than you, and that you would be OK, even if for a few hours. This is where the communication gets scrambled and arguments like this arise.
You have a few "karmic" ties in your charts, which shows that the both of you were brought together to learn something from each other.
This event probably occurred due to the fact transiting Venus formed a difficult aspect with your natal Venus. Venus in the chart describes our relationships. Any difficult transit to this planet can bring about problems. The thing to remember is: this transit is very short, and not usually one that would break people up. You also had transiting Moon aspect your natal Saturn. This can be a time when emotionally (Moon is ones emotions) you are feeling left out in the cold. You two will have contact again, most likely in the next few days. The thing is, you have to work out these issues between your charts and get a better understanding of one another. Him thinking he has to hide out when you two have disagreements isn't going to improve the situation! Might be time for you both to have a talk about things. I have a feeling that near the end of August, you are going to be feeling compelled to let your feelings be known since at that time, transiting Mercury (communication) will be right with your natal Mars (what makes you angry, action). I would avoid any heavy discussion until after August 8th UNLESS you have had this discussion before. Remember, Mercury retrograde is like a "do over" period. So, it may be a time when you revisit what has been talked about before.
I hope this has cleared up some things for you. Take care.
