<human>: I just recently moved in with my SO but I've always had this underlying issue about her texting and snapchatting her ex boyfriend. 

Some backstory on their relationship: they went to high school together and he moved to Portland. She ended up going and moving in with him out there. Their relationship ended because he happens to be a heroin addict, but she's still friends with and talks to him. 

I don't like to be the jealous type. It does bother me a great deal because part of me feels that she still loves him and misses him and that I'm wasting my time. I wonder what kinds of things that he did offer her that I can't as well as questioning my self worth as a whole. I can't tell her that it does bug me because that brings trust issues into play and makes me look like an asshole. It could be a possibility that I'm reading way too far into this and should trust what she says. How should I go about dealing with this?

Can you give me a shortened version of the text?
<bot>: girlfriend still frequently talks to her ex, I don't want to bring problems into our relationship by telling her I'm jealous.
