<human>: Hi /r/relationships. I know my opinion and way of thinking is not going to be popular here, but I do not know what to do:

My girlfriend and I have lived together from 1 year in our relationship til now (2 years total).

Recently (past 2 weeks), I have been thinking about an old highschool friend. We were amazing friends and hit it off, but I was very shy during that period of my life and I never asked her out.

Thinking about my friendship with her, I regret it, and I can't stop thinking about it. It consumes my thoughts.

It doesn't help that my girlfriend and I are fighting and disagreeing about things every week. She wants kids by 29, but I don't want to put a timeframe on it - I want to be financially ready.

We also aren't great at communicating. I want to communicate about our problems right away, while she would rather let things blow over and forget about it.

Every time we fight, I think about leaving, living independently, and then going to this other girl and asking her out. I just want to do it - I don't care if she says no, but the uncertainty is eating away at me.

I can't tell if these thoughts will come and go, as it's all I can think about (and dream about) for the last 2 weeks.

I kind of wish it is a phase, but at the same time, these thoughts are causing me to realize I am not 100% happy in this relationship, and I'm not sure we can work it out.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Problems with currently relationship make me long for an old friendship. I keep thinking the next fight will be our last, and it will give me the opportunity to eventually ask this girl out and get over my regret... It's fucked.
