<human>: Give me the gist of the text in a nutshell

My boyfriend and I have been together for over a year and a half. We are about a one hour drive away from each other but we are both very busy with different lifestyles and school, which results in us seeing each other maybe once a week if we're lucky.

I have always been strong enough to be able to deal with the distance, even if I miss him more than usual sometimes I never consider calling it quits or question if it's worth it. We are very different people and we do disagree on many things (not major things just common opinions) but I can't imagine being with anyone else but him; I love being with him even if we have our differences and I accept him the way he is.
We usually argue because something else in our life is stressing us out a lot, but when it gets harder than usual he brings up old problems from the past, making the situation even worse.

Now, my problem is that when things get out of hand, he questions our relationship. He isn't mature enough yet to be able to always stay positive with how rarely he sees me. It gets to him and he starts questioning if it's worth it. It makes me feel like I'm in an unstable relationship, and he could leave at any point. He has broken up with me in the past, more times than I thought I could take, but he has always come back in a few days. I have never broken up with him.

I would really appreciate advice on what to do, I don't know how to help the situation and it's a lot of emotional pain for me to go through the breakups. I can say that it has gotten better every month and that he is maturing, but it would help a lot if he could commit to me as much as I commit to him. One thing I don't want to do is to break up with him to show him how it feels. I take break ups very seriously, he must take them very differently than I do since he has broken up with me often in the past.
<bot>: Boyfriend breaks up with me often and makes me feel insecure because we don't see each other as often as he would like. What can I do to help him realize that distance doesn't matter if it's true love.
