Bf comes home late everyday literally

So I found out he lies about his work hours. It was obvious but now I have proof. He goes straight to his grandmothers house everyday when he gets of 3:30pm and reach home around 12am. Ik his grandmother went to her country for about a month, she’s probably home and back by now. But he wouldn’t tell me. He still pretends to get off at 6pm, and he wouldnt call to check on our daughter or me all day. He won’t even answer my phone call or text. I spoke to him about all of this but he just Denies everything. He said nothings wrong either so idk.

I have an update but y’all not going to even wanna know smh. Can’t take this.
