Re: I think my girlfriend is cheating on me.
I hate to say it so forwardly, but she is definitely f***ing another dude-bro. Applying makeup to return home? Yeah, to guy she's f***ing's home. Chances are though, you're both young and this guy is offering her something you don't have: money, security, status... who knows. Who really cares?
My current girlfriend was a virgin before we had sex. However, I noticed that since we've been having sex, she's been getting hornier by the minute. That isn't an issue, really. How can I complain, ;). But, her father dying and abandonment issues may lead to her seeking out affection from multiple partners. It's as if she turned into a sex junkie over-night. So far, I have no reason to believe that she is cheating on me. HOWEVER, she has used the "I fell asleep excuse on me" about twice now, in the past two weeks. Something I'm not 100% convinced it true -- f*** that, it's definitely BS. Nonetheless, even if she is lying to me, and eventually does cheat on me, I can leave guilt free.
One thing is for sure, once someone cheats the trust is broken. It is over. You don't need to suffer through the immaturity/deceit of another person, or you'll disregard your self-worth. Trust, and be confidant in yourself, that you can find another. Don't settle for bottom tier pussy.
