My sophomore year in HS on Christmas, my mom found out that my dad was cheating on her. It ended up in a huge fight, jail for one of them, and endless amounts of visits to the courthouse (this lasted 3 years!!!!) Outside of my dad cheating, my grandma cheated on my grandma and straight up left without saying a word to any of us, my uncle cheated on my aunt, and my sisters boyfriends cheated on her. I've been in a relationship with my boyfriend for a long time now, but sometimes I just can't help but to feel insecure and suspicious, even though I trust him with my whole heart. He comes from an amazing family and I believe everything he has ever told me. But sometimes I overthink and I'll start questioning things... Could this be because of my family's past with cheating? Has anyone else gone through something similar? How do you cope with it?
