Yes i used to be very very jealous to the point of starting a fight with any girl he talked to!!!!!
I was like this for 9 years (why he stayed with me i'll never know) the only person hurting all the time was me as you will well know it is a horrible feeling in the pit of your tummy to be jealous.
Eventually i finally got it thru my thick head that if he wants to be with someone else being jealous isn't gonna stop him! Now i think along the lines of if you wanna be with someone else then go it will be your loss!!!
By the way we have been together 15 years and married for 3 of those and have 2 kids
