<human>: I've been with my girlfriend for two years now. We have lived together for just under a year. She has always treated my son well and we have spent lots of time together as a family.
 

A few months ago my gf came to me saying she wasn't happy living with a teenager in the house. I was shocked and pretty devistated. We've been talking through this and trying to figure out what the answer to this is but it looks like she's going to leave. 

I can't understand why this is happening. How did I get here with being in love with someone who loves me and always treats my son well but now is leaving because of him. I'm heart broken and angry. She just keeps saying that life with a child doesn't make her happy. 

It doesn't help that we are that annoying couple that is perfect together (according to others). She's my best friend and the person I would turn to when I feel hurt, but now I don't know who to turn to. 

I'm sorry I'm just lost here. Has anyone gone through this before and can tell me what to do and how this turns out.

Can you give me the gist of the text in a nutshell?
<bot>: My girlfriend is leaving me because she doesn't want to have a life with my son in it. I need advice from other single parents on how to cope with this.
