Boyfriend suggested to go work w his ex.

So my boyfriend has been working on getting veneers and so he’s had to take unexpected time off work because the temporary teeth keep breaking off, and so his boss fired him today. He’s going to go talk to him to try to get the job back but I saw he had texted his old boss, this is where he worked when we first got together. The issue I have with this is that’s where his old bitch works with. (She is married with kids, they had An affair Before we got together)

I do trust him at this point but when he worked there before he would be at the shop where she works and would never answer my phone calls until 30 minutes after then say he was smoking and talking with the guys.

EITHER way I’m just not comfortable with him going back there and I told him that. I don’t currently have a job because we are sharing a car due to me selling mine because I moved across the country with him for a job opportunity, and I’m 7 months pregnant so it’s been tough.

When I saw that I told him I don’t feel comfortable and he said well if that’s my only option (which it is not) he is going back there. And I said well that would really piss me off - and he goes don’t tell ME what to do while you lay there (it’s morning and I had just woken up)....

I wasn’t rude about it, I was just like I don’t want that. Plus that old job he did a lot of cocaine and shit with the guys that worked there. Am I overreacting????
