Your last post gives us some explanation of why he is as insecure as he is. It's not because of you, it's because of his past - can you see why members are posting that it is not You, your sexual past/financial situation but what he himself is lacking?

It sounds as though he projects insecurities onto you, and you seem prone to self blame (I understand, I am prone to that too) so you accept it, but you are unhappy. It isn't healthy or fair that he does this.

I know you mentioned he is in therapy so hopefully his therapist is working with him to address his insecurities. Projecting it on to you is no answer and will likely destroy love and trust over time. Please don't accept this.
