Title sums it up. I(F19) was in a relationship with a guy(M20) for 3 &amp;1/2 years and he cheated on me constantly and would openly express his interest in other girls including my friends and sisters. Now i’m dating a guy(M27) which previously had a relationship where he was cheated on constantly too, and now I feel insecure and skeptical if he even likes me. I trust him but at the same time i don’t trust him. At least not fully even though he’s given me no reason not to.
