Help me...

Thank you for your advice ladies. I've just booked an appointment privately. 

Therapy. Now. Pay out of pocket for a psychologist to help you work through this. Remove yourself immediately from situations where you are seeking attention (and more) from men other than your husband. This means stop going to bars, stop talking to friends who are supporting you in this lifestyle, get off the internet where you're meeting men, stop it. Now.

There are low-cost therapy options pretty much everywhere. Google your town's name + low cost therapy. You can even find students (MSW or psychotherapist) who are getting their required practice hours (always under supervision) for very low cost or free. Talking to someone is the first step. I would also check out any group therapy/support groups or services through community centre, church or local programs like AA.
