I’m making mistakes.

I feel for a guy who wasn’t single, we messed around, then they broke up but we never become something serious and he met another girl and now they’re married. I was so hurt, so so hurt, even though I did something wrong, but then I met a guy who was at the end of a relationship, we did stuff while he was breaking it off, we fooled around and now he’s found another girl and is starting a relationship with her. I feel so hurt but it’s my fault and I deserve it I feel like a bad person and I’m going to spend my life making mistakes the same ones. I believe in everything though, no sex before marriage, no adultery, I don’t sleep around or drink. I feel so lost in life and need help. I’m feel like I still feel so much for the second guy but… theres nothing I can do. Help me to become a good person.
