Cheating accusations whiles pregnant

Mabel

My partner is constantly accusing me of cheating and I’m 35 weeks pregnant yet he won’t stop with the accusations. He has t been very supportive of this pregnancy, his mood switches up here and there and makes up this scenarios and assumptions that I’m talking to someone. We both wanted this baby because it’s our first but I can’t around why a man will accuse a heavily pregnant woman of cheating!
