Feeling insecure

My fiance and I have been together for 2 yrs but have known each other since we were kids. During the first year things were just the greatest, getting to know each other building a trusting relationship. And then he started talking about these women who wanted to check him out. He then told me that these same women where messaging him and sending him pics. He would forward them to me..EVERYTHING!! The messages and pictures. This really bothered me and still does when he talks about these women. And I tell him everything. I get very insecure because of this!!

I have given him an ultimatum. It was" if you continue replying to these women and giving them hope that there is a chance of any kind of relationship, its over between us!" Even though that was hard enough to think it had to be done!!

Since this, he has cut off all ties to any social media and cut off his cell phone. The only way anyone can get ahold of him is going to his place.

But he dreams of these women from time to time and tells me. That really bothers me that he dreams of them. Hell!! These women knew that he was engaged and yet they went as far as coming to get him when we got into an argument...more than once! This makes me feel real insecure about myself, and I was a confident women until these women decided they wanted my fiance!!
