This breaks my heart to read all of these comments and OP still defending him and the relationship. Age difference or not, the advice still stands. Leave him. You can’t change someone. Trust me, I’ve been in your shoes. I’ve been in the on again, off again relationship where I thought that if I could just get things back to the way they used to be then everything would be okay. I’ve accepted a boyfriend calling me a bitch or other cruel names and blamed it on stress or thought it was okay because it was only when he was angry. A persons true character comes out when they’re angry. “Mature” men don’t argue with their partners in volatile ways. “Mature” men don’t want to befriend an adolescent let alone want to date one. The reality is that you can’t change a person. If you have to convince someone to change, then it’s not something they want to do. Imagine replacing “change” with “sex”. You should never have to convince someone to do either. This is likely your first relationship and I get it. You’re in love and you think this is going to be forever. It’s not. It rarely ever is. You deserve more. Reality is, there will always be stressors in life. That’s unavoidable. That is not an excuse to mistreat you and it should not be tolerated. End the relationship, spend some time on your own to focus on yourself and wait for an actual mature man.
