You know you've been had. You can see through the lies and it hurts. You feel cheated and used.
When these things happen in a relationship, it is time to make the break.
Breaking up is hard to do, but if the relationship isn't working, you have to make that clean break.
You feel defenseless, but in reality, you are empowered. It's your call and you have to make it.
Never feel forced into something you don't like. Don't let anyone guilt you into doing something you aren't comfortable with.
The hurt may never go away, but you will heal and you will survive.
