Where to start ! So I'm 6 months pregnant been with my partner for 4 years. Since I was about 8 weeks his behaviour started to change. Over the last 2 weekends he has stayed out both sat and sun night at a "mates" I've never met. We booked 4 days away self catering tomorrow and kids are so excited. He's gone again no contact phone off. I called him out on his behaviour this morning on rhe phone and he just didn't come back home. I have to take the kids away they'll be so disappointed but i know i will hate it and be upset. He's basically stonewalling me. My instinct says he's up to no good and I am devastated he has done this. I just need hand holding because I am shocked and upset and lonely. I dont know what I did to deserve it.TIA
