Lying

Edit* I know it was innocent because there’s been my friends with him who wouldn’t lie to me about it.

If your partner lied to you about where they were even though it was completely innocent what would you do?

About a month and a half ago my partner lied that he was home even though he wasn’t and was at a house party, he didn’t cheat or anything like that just lied about his whereabouts. I told him at the time that I don’t tolerate lying and he said he wouldn’t do it again.

Today he as lied again about where he was, even though again it was completely innocent and he had just stayed at his friends.

We aren’t living together at the moment but I am 15 weeks pregnant.

If I wasn’t pregnant I would have broken up with him this time as I cannot stand lying. I love him with everything I have and I want to be with him, especially with the baby but I just don’t know what to do. What would you do?
