Cindy best advice, you are better off without him.
Of course one day her wandering eye will find her her next acquisition. Life will be good for them for the short term, then the mistrust will take over, it's what normally happens.
Life will get better once the hurt wears off, one day in the future you will meet one of the good guys and live a better life than you could with a womaniser. Forgiving this sort of behaviour always allows them the green light to do it again, trust goes out the window. So when you can move on, put on the lipgloss and find someone worthy of you. Yes it happened to me many many years ago, I did find someone else and 25 years on we laugh at how ridiculous our first marriages were and how happy we still are. By the way both our ex's strangely broke up soon after with their new partners! They have both had rubbish life's since!
