The guilty person who doesn't want to change will always shift the blame.
The solution to what this person is calling 'your jealousy' is to find a man who values fidelity and who wants to be faithful to you.
My guess is you may be appearing too accepting (in general) and men who want to take advantage latch onto to women like that (and as you have found out -- in multiples!)
Value yourself as the special, unique person you are and accept no less than the respect you deserve.
