I don't even HAVE a gf as of rn but I'm constantly in the back of my mind in this mindset that I can't trust any girl. I'm not in seddit for hook ups but more LTRs and I just always envision getting cheated on and it's not healthy.

Fidelity is something that I value dearly and I feel like if I can't even trust a girl then the foundation will obviously be very weak. How do I get out of this mindset?
