When you suspect your partner of cheating and they tell you that you're insecure it probably means they are cheating. Every case is different so dont quote me or do I dont care. That insecure word gets thrown around alot but if you have a feeling I say go for it. I dont care if someone im dating goes through my phone or follows me because I have nothing to hide.
Ill admit upfront after getting burned and watching too many episodes of "Cheaters" and Maury Povich DNA tests Im more paranoid than most people but I would rather be called "insecure" than a "sucker". There is alot more at stake than just getting your heartbroken there are diseases. If you are man you should have a choice if you want to raise another mans child it shouldnt be decided for you by a cheating spouse who lies about you as the only possible father.
