Okay, so to make a long stor short, I basically left this guy I was dating and had something solid with for a "Summer Fling" that ended up being something bigger, but ended horribly. It hurt the guy I was dating a lot because I cut off all communication on purpose, as I thought I was going somewhere with the new guy. However, after realizing how I was being played by the Summer person(I was just getting used to get an ex jealous), I started talking to my original guy again, but now I'm confused. I really like and completely want him, but I'm afraid of the damage I did, since it does have consequences. My self-esteem has been shattered, and I'm scared of messing things up again.
This guy and I are back together as we were before, and he has told me he understands what happened. We have gone on dates and seem to do pretty well, but he did get hurt pretty badly and I made him cry once by rejecting him. I feel like I ran away from him but then realize how good I had it, and I want to keep that. We keep going on dates, are affectionate, have sex, etc. but he doesn't text me that often and instead just says "We'll talk about this when I see you." It seems cold, but he had told me before that he could text me all day but has to control his feelings. He is a very responsible and career-focused guy who also has a huge heart.
Now, he is busy and is older than me, but why does he do that? It makes me insecure about how much he likes me and makes me think he is still kind of bitter, as much as he might try to not be. Last time he told me "that's when I used to like you more" when we talked about something that happened this year before Summer. He always responds to my texts, but why am I so insecure? I just want him and don't want to lose something so great I had due to a stupid mistake...
Please help; thanks.
