I need advice. I keep finding messages in my boyfriends phone where he messages other girls who are his “friends”. I found one saying “oh you’re bored, let’s make it interesting”. I don’t know what to do. He never did anything physically with them but there were texts that didn’t sit well with me. He’s cheated on me before but swears he hasn’t done it. We live together and I don’t want to make the same mistake again.
