Am I wrong ?

My boyfriend and I have a 10 month old. He has bipolar. When we first got together years ago, he had trouble keeping a job because of it. If that were to happen now. I would be out, but honestly I was young (16) and dumb so I didn’t think much of it. Through that time, he was starting to become stable and I felt comfortable enough letting him buy an Apple Watch off of me and just make payments every other week. Well he lost that job too and I was out a decent amount of money. We are older now (22 and 23) so I don’t remember exactly how much but I think it was around $200.

Obviously that was years ago, and he has become stable in jobs, so I let it go. However, a few months ago we went through a time where he was financially responsible again because he went off his pills. He went through a manic phase, stopped paying for ANYTHING for baby for months, lied saying he was spending money on bills when in reality he was buying luxury clothes. Meanwhile I’m a stay at home mom, he sat back, letting me use savings to buy EVERYTHING for baby. I only stayed because he promised to get back on pills and work on becoming financially independent. He was doing better, or so I thought. Then this week, twice he said he wanted to make the night special and go out to dinner so he asked me if he could borrow the money to take us out and he would pay me for it today. It was $100 total. Well today he tells me that they locked his account because he is $600 behind on his car payment. I am really pissed because A) obviously I won’t be getting THIS money back either. B) That’s money that could have gone towards baby and instead it goes to unnecessary eating out and C) I’m sick of everything coming out of my pocket the last couple months

I know people will say “well obviously if he had to borrow it it should have been a red flag” but he really had me believing he was more stable 🤦🏼‍♀️🤦🏼‍♀️
