Does wanting alone time mean it's over?

Hi, I've been dating my boyfriend for three months now and it has been really truly great. He has a son (7), who lives with him most of the time but he has been great with devoting time to me when his son is with his ex. He is very communicative about his feelings and just over a month in told me he loved me which he then continued to say daily. We exchange lots of quick little texts throughout the day with little sweet messages and talk just about every night. He has spoken openly about marriage and although I haven't met his son as of yet, he has spoken of the meeting. Two weeks ago, he and his son left for a 10 day vacation during which time our calls and texts decreased but they still had the same kind of content. He came back last Sunday (one week ago) to a mountain of work both at home and at the office and I know he felt overwhelmed by all that he had to do. His son's mother is out of the country on vacation so he hasn't had anyone to help take care of his son. We have only spoken twice on the phone this past week and his texts have become fewer and less romantic and his response time was longer. Now, I know I don't bombard him with texts when he's at work or with his son; I take my cues from his responses. As of Friday, I had sent a couple which went unanswered entirely. Last night was his first free night without his son and we had planned on spending it together (we haven't seen each other since the day he left). When I asked him yesterday via text what the plan was, his answer was very terse: "I want to be alone tonight." I said ok and I haven't heard from him since. Naturally I was hurt and disappointed that he would rather be by himself than see the woman he says he loves. I'm very concerned that he is feeling overwhelmed in some way and that this is the first step in his ending our relationship. I'm the only part of his life that he could, in theory, she'd to make things easier. I haven't tried to contact him and don't plan on it; I'll wait to hear from him. Anyone have any insight into what he might be thinking, etc? How worried should I be? Please help!

You have a pretty new relationship. 3 months is not a long time so it is hard for you I'm sure, to really know what he is thinking. I want to say no matter how much of a load he has, that is no excuse for rude behavior on his behalf. You were only trying to be the supportive partner that you should be. I think you are correct in not contacting him. He hasn't replied to your text and then canceled a date you two had. It is his job now to contact you and also to apologize for his behavior. He could have spent a little time to explain if he needed time to work on things. He should prioritize you up there with work and child care if he really meant what he said when he told you he loved you. When you are having a difficult time and are stressed it is natural to want to be with those whom you care about, and especially your significant other, to get support and love from them. The fact that he would rather be alone then with you is a warning flag. This is a relatively new relationship. You need to set the standard now. If/when he decides to contact you again you need to let him know that his rudeness is not warranted or appreciated by you. You understand his frustrating situation but that is no reason to take it out on you. If he needs some time to work stuff out then he needs to communicate that with you and not just ignore you and cancel dates. You have a life too and shouldn't be kept waiting on what ever it is he decides to do. You are being very patient and understanding but do not let him treat you poorly. If he thinks his behavior is acceptable now then he will continue to do it in the future and you will continue to have your feelings hurt.
