So my ex boyfriend had a roommate who had a friend who hit on me TWICE. First time he was sober; second time he was drunk. I told my ex when he got home from his job (I would stay at his house while he worked) and all he said was is that "you should take it as a compliment. He thinks you're cute. What do you want me to do? Punch him in the face?' I was rather disappointed and discouraged with his response. I didn't understand why it didn't bother him when it bothered ME. It made ME uncomfortable. Then the second time the same guy came over, I tried to avoid him and watched TV while him and the roommate hung out. I was polite but kept my distance until he wanted to hug me. I was just wanting to be civil and keep the peace so I hugged him back even though I didn't want you to and he kissed me on the head. I told my ex boyfriend again when he came home from work and my ex took the roommate's side because he was friends with my ex. The roommate and his friend borh denied it happened, so it made me look like a liar when I told the truth. My ex always claimed he's neutral but clearly wasn't true. 

Months after we broke up, he has another girlfriend and he wrote on her Facebook page before I blocked them both, that guys should respect that she has a boyfriend who makes her happy. He clearly had a way different reaction. 

I feel traumatized by the whole situation that I'm worried that I'll never have a healthy relationship with anyone because they'll pick their friends over me.

It wasn't wrong to expect my ex to have stuck up for me when he sticks up for her.
