I have been seeing a lovely man for about 4/5 months and we get on really well. It's my first time of dating since I lost my DH just over a year ago. This guy is really great, not pushy, very loving and considerate,he thinks the world of me and is a good father to his 7yo son whom he has regularly. When I am with him everything is great, but when I am not with him I get so jealous over his ex wife.They have been apart for 6 years but still get on very well, to the point where they occasionally go out together with their son, and share his birthday etc. He has invited me to meet her but I just don't want to. Knowing what she is like won't make me not feel jealous when he's with her. I don't for one moment think they will get back together, or that anything's going on with them, it's just that I can't bear the thought of him being so friendly with her still, its as if they are in a little club that I can never join because of their shared history.
Am I being really stupid? If so how can I try and get rid of these thoughts and feelings I have whenever I know he's seeing her? I am worried that my jealousy (and I'm not normaly a jealous person on the whole) will destroy our relationship and I don't want that. I have never mentioned this to him as I don't want him to think I'm really horrible, because I'm not.
