To be fair, he is dealing with a LOT. Stuff no normal college student would usually be dealing with. And I really, really love him. Last night I just sort of snapped. I think I created a lot of the situation myself, by not listening when I should have been, or being clear enough about my feelings. I definitely have a lot to work through myself.
We fought (and I can count on one hand the number of times we've really fought in the last four years) and then we talked, and I think I got through a bit. He broke down today over all the things he's been stressing over and told me the last thing he wants is for me to leave him. I think we just need to rework some boundaries and stick to them. He needs to be more attentive, and I need to be more assertive...I think. I'm not super experienced in long term relationships. I'm just hoping it sticks, that things don't just revert back to the way they were. Because I'm not an on-call girlfriend, in a relationship when he needs me to be. You know what I mean?
Thank you both for your advice!
