<human>: We was together for nearly 6 years she was and still is the love of my life. I was just bad at showing my love/attention. It's 99% my fault we split I know that. I needed/need to show her more love, as we were she didn't even know if I loved her or not. Wasn't good.

The last few months of our relationship she started talking a lot to one guy, he was there for her when I wasn't she had someone to speak to... Which SHOULD have been me, but I was useless like that.

When we split she didn't go straight to him, but I knew it'd happen. We stayed very close. Going for meals sometimes and always chatting. She told me the other day that she has started seeing him. She said she likes him a lot but it's not the same as when she was with me. When she first met me she knew she loved me and she still does. She still wants to be with me. 

She keeps telling me she has no idea what to do. I think I've changed. I KNOW I can change for her, it just took me way too long to say it.

I honestly don't know what I should do.. Should I let her carry on with this guy? Who does show her attention, does show her love.. makes her happy.. all the things I haven't for so long. Or do I try to get another chance and potentially screw it up.. That way I would have screwed her up even more and her chances with this other guy would have vanished. 

I've told her I have no hard feelings for her getting together with this guy. I 1000% understand why she has, I wasn't a good boyfriend towards the end.  He was there and he was showing her love/affection. She keeps saying she does feel bad for being with him though. 

One thing she said the other day to me about him. He asked her why she was looking at him like she was and apparently she was just zoned out thinking at what she was doing with him and why she wasn't with me.

Give me a shortened version of the text
<bot>: Not sure if I will just screw her up more.. should I let her try to work it out with the other guy?
