I have been dating my boyfriend for two years. In the beginning, I found out that he had cheated on his ex-girlfriend, which left me feeling insecure. He assured me he had changed, but I couldn’t shake the feeling that he might do it again.

Over time, I became more controlling. I check his phone, ask where he’s going, and get upset if he talks to other women even if it's just casually. I know it’s not healthy, but I’m terrified of being hurt like his ex was. He says I'm suffocating him, and it's causing constant arguments.

I love him, but I don’t know how to stop feeling this way. Am I the asshole for being so controlling, or am I just protecting myself?
