Is jealousy bad in a relationship?

I’m just gonna come out and say it: I get jealous when my boyfriend hangs out and texts his female coworker friends. Mind you, he spends time with me, and shows me plenty of attention, and I trust him, but I personally get so envious of other women he associates with...and I HATE IT. I want to change so badly. I’ve met his female friends, and they are lovely, wonderful women. I’ve been fucked over BIG TIME in the past by female friends and other women who tried stealing a guy I dated or tried to sabotage my happiness, or isolate themselves when something good was happening in my life, so it’s hard to shake off what I went through. I just assume those women are going to do the same thing and go after him, and they are just clever enough to get away with it.

Have any of you women experienced this? How did you deal with it and get rid of those feelings of jealously?

THANKS ❤️🧡💛
