<human>: 28/m and she is 26/f. Dating 5 months.

She was married for 7 years and is currently separated and waiting for her divorce to be finalized. No kids.

We love each other and everything in the relationship is great except she still communicates regularly with her ex, who wants to work things out. She has a really hard time feeling guilty about leaving her ex and doesn't want to cause him more pain than is necessary, and so she feels like still talking to him and not making it clearer that it's over will somehow make the situation better. But at some point I feel like continued contact causes more pain to everyone involved than just severing all ties and moving on. 

Specifically, she still talks to her ex via facebook and phone on a daily basis. She is always very secretive about the times she is texting or calling him because I think she feels awkward about it and how it makes me feel, but she still does it anyway. 

I don't want to shade this question with more specifics of our situation, but what level of contact do you think is acceptable with an ex that still wants to have a relationship with the person you're seeing? Would you tell her that she needs to stop calling and texting with him? Block him from facebook?

I guess I just need to communicate better how uncomfortable it makes me feel, but I've brought it up before and it's like she is more worried about hurting him than how I feel about it. I don't want to come off as controlling/insecure/inconsiderate, but at the same time I feel like there isn't anyone in the world who would be OK with this. I guess at some level I wish she understood this herself without me having to bring it up and make it a big deal, but I don't think it's going to stop unless I make it clear that it's a problem that only has one solution. Am I wrong here? Should I butt out and let her deal with him however she wants?  I think it would maybe be fine to contact him in the future after he's gotten over her, but until then I don't see how anything good can come of continued contact other than soothing her guilt, which is just a selfish reason.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: GF still talks and texts with her ex who wants to get back together with her. It makes me really uncomfortable. What is OK to expect from her regarding communication with her ex?
