Am I being unreasonable ?

I'm 34 weeks pregnant and for the past few days I've started to experience very sore pains down below almost like period cramps.

My partner has been drinking every day after work 1 or 2 beers cause "he's stressed " at the weekends he seems to be drinking every weekend. Either in the house or with his friends.

Today he went out from 10am playing football with his mates and then stayed out to drink after and didn't come home till half 7 at night .

We were arguing the whole time because I wasn't happy with him being out drinking all day. Especially that he drinks every weekend ...

Anything could happen and he's out drinking.. I was experiencing pains down below again today and had to ring hospital ... And he accused me of lying... saying nothing is wrong that I'm just pretending to be sore so he comes home...

Wdf? Am I wrong to be going mad at him for being out all day drinking ?? Especially when I have 6 weeks to Go??
