sweetie, it's ONLY been two weeks. for both of you.
the fact that you in some ways are more concerned about what women he might meet than the true purpose of detox/treatment, your own admitted insecurities and jealousies is actually your own INVITATION to start recovery work for YOU. now is the time to find support, put the focus on you and grow towards being happy healthy and whole!
by the way, your anger is ok. your jealousy is ok. they are simply "spokespersons" for the inner you that wants help too!
