Re: major jealousy
The one thing I tell myself when i feel jealous of someone attractive is that the whole worl is full of attractive people. So do you, everytime you see a real attractive man, seriously think of cheating and starting something with that guy just because he is attractive? No doubt your fiance will notice really gorgious women just like you will notice real gorgious men - everyone does that and its not a choice. When your fiancé cheated with his ex, it was because he fell in love with you and it also meant that he left behind his past and started something with you. In my eyes that is only fair even if it hurt someone.
The other thing I thought of was what is it that makes you feel so inferior to these other women? Do you feel like you havent taken care of your physical appearance enough? Do you define yourself overly through factors like attractiveness? What is it that your fiance loves about you? And would you feel so threatened by another women if you thought "damn she is soooo extremely nice?"
Ok here is my suggestion: if its something to do with your own appearance, do things that make you feel as an attractive woman again- whatever that is. Get your hair done, sign up in the gym, go out with other women, do a dance class etc etc. Try to find out what makes you think that the other women are somehow better than you (believe me, they are not!). The thing is, if you can find your own security back, it will make yourself so much more attractive....your partner probably doesnt really want a woman who is in need for reassurance but someone who knows their own value and loves themselves. The other thing is to maybe learn to let go of the panic. Life is a risk and bad things can always happen (not saying they will) but accept that if your partner wants to go he can go with whoever (because thats reality) but if he stays I think you can assume that he wants to be there with you. If he cheats (personally, I dont think so) it would be painful for you but you are strong and clever and even then, you will be able to move on and deal with it.
