I think the moving out might be causing you to become a little unhinged which is why you're more emotional lately. It's all okay, though. I don't think you messed anything up really.
On 37K how much support would you really be getting from her? I think this is one thing I'll say I would strongly recommend you don't seek from her - at all. It's something she cited as a reason for leaving (I believe, right - about your work) and so I'd just find work before I'd ask for that support.
It seems you're trying to get something from her to compensate for something - spousal support, talking about the mattress or what she's taking. Let all that go-
I think her being in europe might be some kind of relief for you. I'm relieved now that I know my BF is in a hotel, and I can get a real bonafide break - no pressure on me to db or show him this or that. He's just gone for a while and comes to see D but its given me some peace.
Try reframing stuff when you can.
And as far as her spending, that's her problem - maybe if she's moving she had to incur more expenses this month? Either way - nothing you need to worry about now.
Funny, my bf changed his cc statements from coming here before he even moved out. Who knows what that means. Don't care actually.
