<human>: Can you condense the text into three sentences or less?

So my on-off longtime high school sweetheart and I broke up Sunday morning on her request, though I didn't try to argue or ask her to stay, as we've been through this before. - [Link for the lazy](

A lot of our issues centered around communication due to frequent long distance, but as much as I love(d?) her, there were some arguments that seemed to come out of a sense of insecurity(both of us have had instances in the past (almost 2 years ago) where we thought the other engaged in some level of infidelity), immaturity, or maybe a subconscious desire to argue just to talk more and have my attention. 

With sometimes more than a few small arguments a week (none really lasting more than a couple angry hours max, but still frustrating), she would get upset about things like whether or not my text responses seemed enthusiastic enough, or when she's not in the mood and I am- which makes her upset because no matter how I react she thinks I'm intentionally trying to make her feel bad about it. 

Sometimes she would question the way I feel, or ask me questions about my feelings that admittedly made me uncomfortable (I usually tried to give reassuring, caring answers, but am I in the wrong for having been slightly offended or pushed back by her need to ask such questions?)

With the recent split, I'm trying to move on but also understand that there's a strong possibility we will end up together again in the future when the time is right - not really looking for any feedback on that.

What I am curious about however is, has anyone ever been in a relationship where constant fighting or arguing was an issue and then resolved that issue? Can something like just be caused by a need to grow up a little? What does that take?
<bot>: Recently split with SO because current long distance situation exacerbated arguments - have you ever been in a relationship where constant fighting was an issue, and then you both resolved that issue? Is that normal? What did it take?
