sabotaging my ttc

It seems every month I sabotage my chances of ttc with mood swings but I honestly don't trust him. He constantly tells me I am over reacting and by the time I want to reconcile my window is closed.

Now this month I am upset because of a female cousin that visits our home with different female home girls. When she arrives she either calls him on the phone to come outside or hit the horn for him to come outside.

I have spoken to him about this and how it makes me feel. Of course he thinks I am over reacting.

About two days ago ... She came by she called and he left.. I looked out the window and seen his cousin and a homegirl... I waited 30 minutes and called him. Asking him where he was and who he was with.. He lied and said just him and his cousin.. Then when he got back I was obviously looking out the window so he can see I know he lied.. Then he came in the house and lied again

Now today his cousin was calling but he ignored the call.. When I asked why he ignored the call He gave me a blow off response

Then later I notice he has downloaded an app to hide incoming calls until you slide to reveal.

I am so pissed I don't know what to say to him

I really want to believe him and not over react but when he take time to block his phone calls .. 🙍..I just can't

Thoughts...?
