So I've been in this relationship for three years. We have a kid together. We haven't fought much. Until recently. Suddenly I am being questioned for everything I do. Suddenly everything I do must be cheating. Suddenly he's checking my phone when he thinks I'm sleeping and coming up with all sorts of scenarios that allegedly lead to me cheating. He's telling all his Co workers and our mutual friends that I am cheating. He even said because I talked to my sister for an hour instead of being all over him that it is a sign I am cheating. I'm starting to not want to be home or around him anymore. I also don't want to throw away the last three years. I've tried to consult with close friends and they say maybe he is the one who is cheating. I just don't think that is the case but I also don't understand why this is happening.
