Background info: 23 y/o female, Bipolar II, BPD, &amp; a butt-load of anxiety disorders. So there's this guy who I feel like I really clicked with at the beginning of our relationship in ways people normally click. Then I had a hypomanic episode and we ended up hanging out a lot, and looking back on it, I split completely white on him during that time. Now, however, I'm leveled out again and I've noticed a weird change in my attitude about him. When I'm with him, everything's cool and he's fucking amazing. But when I haven't seen him for a few days, I split negative on him pretty badly. I don't want to say I split completely black, but it's enough to the point where I resent him and use passive/micro-aggressions if we're texting. It's like the splitting's happening simultaneously.

Has anyone else split like this before? I really want this friendship to work out, so how do I ground myself and stop the splitting?
