<human>: Can you condense the text into a few key points?

So, I am currently living with my girlfriend of sixish months. We are perfectly happy together, even looking at buying a house!

However...I have an ex...we were together for just about 4 years. We have broken up for 3 months before. Lived with other people, our families hate eachother, we technically don't function together. We argued constantly, wanted different things from life, and could almost never agree on anything. Except for the absolutely unrelenting want to make each other as happy as possible. 

We had gone about 6 months without being in any sort of contact...and then we broke the seal and started texting. Couldn't even honestly tell you how or why. 

Now this isn't really about "oh should I go be with my ex!" this is more, wanting to validate my own sanity level. 

Does anyone here have an ex they just can't keep away from? No matter how many issues, fights, problems the entire thing has, you just cannot stay away?

Maybe more importantly, have you learned how to get away from them if they did exist? Not that I'm honestly sure I want to get away from her...
<bot>: Have ex that I'm still in love with, can't get away, not even sure if i want to. Do you have this too?
