hmmmm WHY if you are BF/GF is he out partying around those kind of women if he's committed to you?

This isn't about you being insecure as it is questioning his REAL committment to you BASED solely on his behavior. Depending on his REAL level of committment you have a RIGHT to question his behavior as being non-supportive of you.....honestly I wouldn't be feeling jealous but I would be feeling DOUBT about him & whether he was TRULY INVESTED in your relationship.

His partying around women like that without you being with him shows total lack of support toward you & your situation of being a recovering alcoholic. If that's the kind of support he gives you now, he doesn't sound very serious truly caring about you & the relationship between you with his values that seem to be stronger toward partying than what is best for you.

Maybe your feeling of jealousy is more an internal warning about something being not quite right with the relationship & you are not seeing it for what it's really pointing out?
