Actually, no mystery at all. I solved one issue by actually talking with a friend. Yes, I make her uncomfortable sometimes because she knows I get upset when I'm around my ex, and doesn't like to see me hurt. OK, so, does that mean I don't talk to her about it? Likely not. And she needs to make sure it doesn't seem like she HAS to have both he and I together at the same time, so will sometimes NOT invite me over when she's inviting him over, and vice versa. Damn, she puts a lot of thought into it - a very good friend. Though I would prefer if she got over the seeing me hurt thing, but then she'd be a zombie, and it'd be hard to be friends with a zombie because I'd always be afraid of losing some flesh.
I was going to post a picture of snot, but instead found a band named Snot. enjoy!
