My partner and I have a 4 month old. During the pregnancy and since the baby has been born he will occasionally (roughly once a month) after having a few drinks will say he is going outside for a cigarette or food but will actually go to the local pub leaving me with my our baby. My partner has a history of cheating on previous partners (not me) and has recently told me after returning from a solo pub trip and a woman tried it on with him at the pub and it happens all the time. It has now got to the point that I feel incredibly anxious every time he has a drink even if I am having a drink with him that he will just leave and might then cheat on me. When I try and speak to him about it when he gets home he gets very defensive, says I’m over reacting or controlling and threatens to leave or does leave. Currently my self esteem is at an all time low as I am still on maternity leave and he is about to be off work for 6 weeks as he is a teacher. I need some advice as I cannot continue in this current state.
