<human>: i recently over the past couple months have been having some difficulty in the relationship I've been having with my GF of 3 years and BF of 7. She's my best friend but I've pushed her away and needed some space from her and been distant. Sex slowed down and its been a lot less of a heavy relationship but still laughing and having fun. 

   i had jumped on the computer the other day and she had her imsg up and even though I'm a big supporter of privacy and not snooping, i had a drink before and decided to go through it. i found out she had been very vulgary sexting a guy and send him a picture of her butt. She had some some intimate things also(i wanna lay with you, i wanna be with you). 

   i have no idea how to react to this. i freaked out and told her i want to end the relationship and she has a month to figure out whats going on and to get stuff together. She tried saying that i pushed her away and that she wasn't getting what she needed from me. i admit that i had put her at arms length and wasn't doing the things i need. But is this something that i should have to put up with? this quickly(within weeks) she reached out to someone like that. i told her she wasn't even looking for someone to just talk to, she took it to the maximum level immediately.

   i love her so much and am so scared to let her go, she doesn't have anyone but me. I don't want to abandon her and have her try to fend for herself when she has nothing. I'm so hurt that she did this but can't help blame myself partially. I'm so torn between the two thoughts. i don't want to let her go, but i can't look at myself just having someone do this to me and i just let it go

Can you provide a brief rundown of the text in within 3 sentences?
