I'm going to leave my girlfriend.

We have been together for 2 1/2 years, but I think it's time.
I'm no longer attracted to her
We have grown apart
She is constantly distracted by her phone
I am distracted by my aquarium
She wants to get married and have kids asap, I don't
I have found myself attracted to another woman
I've cheated on her (with the aforementioned woman, 7 years my junior)
It's time to man up and do it.

I'm ready to do it, but it's scary. We live together, in a house we picked out together, with our two dogs. Our families are compatible. We used to get along so well. Somewhere, though, something changed. We started fighting, our sex life went to pot (see: nonexistant), and tv/Facebook became a priority. I've utterly lost interest and have no interest in fixing it. She's neurotypical and has a really hard time dealing with my BPD which leads to more fights. I've been married once before and divorced, so I'm equipped to handle the stress, but I know it's going to be tough. There are no guarantees. The woman I have been seeing is amazing and supportive and is here for me...for now. I don't know if it's a serious thing or a fling or what, but it makes me happy and keeps my moods a little more stable.

I'm going to move out Saturday. Wish me luck.
