Feeling sad that my ex lied a lot during our relationship?

I (32F) dated a guy (30M) just for three months, and I really cared for him. However, after the breakup, I realized that he lied a lot and it wasn’t even a white lie - it was to cover his mistake up and I’m upset.

Long story short, before we got exclusive, I found out that he was liking thirst trap photos on Instagram and I explicitly told him that I don’t want to date him if he wants to continue with that behavior since I understand that men who are single might do such thing. His response was, “I respect your boundaries”. I have been previously cheated on so I know I have trust issues, but his response made me feel relief.

However, I caught him doing it twice - first time he got defensive (albeit I was hurt and came in hot) and lied straight to my face and said it’s someone he knows (it was a porn star), which I later realized he lied. He kept defending himself and said his friends do it too so it’s Normal and said I was being insecure. I explained to him that I don’t mind him watching porn, but Instagram feels a little too personal and he agreed, but didn’t apologize until his sister talked to him about it. I ended up going to therapy to address my trust issues and I asked that he stop this behavior and he agreed.

The second time hurt the most because I gained trust back in him and things were supposed to be good, until I saw that he liked a girl’s photo of herself showing off her butt in leggings and I completely lost it. I sent him a screenshot and an angry text, and he got defensive and lied again and said he didn’t lie so whatever. I ended up apologizing for my mean text but he never apologized.

I’m just so hurt that he cares so little about my feelings and lied straight to my face.
