I have no idea what's going on at this point.

That is always a very difficult situation to be in. I would start by thinking of yourself first and asking if the stress is worth it. The hardest part of anything is leaving. I think that you aren't getting enough from this relationship; as you stated. So if you're not getting what you want/were expecting, perhaps you have to evaluate how much effort you want to put forth to continue things. If that answer is anything less than your all, then you should save yourself and move on. As awesome as love and relationships are, sometimes it is not enough, you know? Sometimes it doesn't matter how much you care for each other- conflicting schedules and expectations can be the breaking factor and should be a major consideration in a situation like this.

I don't think that breaking up over texts is ever a very good idea- so at the least, if you are going to, I would call. I think it's the polite thing to do. Don't feel guilty about thinking of another relationship- it's something everyone goes through when they are not getting fulfilled in their current one. Otherwise there would be no desire to part ways.

Regardless, whatever you decide, I hope that it goes well and that the situation improves. The best course of action would be to follow what your heart is telling you to do since no one else can give that answer. c: Feel better!
