everyday is a bad day

every single day me and my boyfriend have a problem, but it's always me. I either get upset when he can't talk to me, he's talking to a hoe who's his friend (she really is a hoe), when he defends his friends over me, etc. I honestly think its because of my environment, its negative because of my mom and her husband (stepdad) he doesnt like me and she always defends him, not to mention she's strict and unreasonable. so I think their problems are affecting my relationship, idk how to stop this negativity. I meditate but it's not enough, I'm okay when I'm physically with my boyfriend, but I know I can't always be right now. I just don't know how to be more happy and less negative
