<human>: Can you condense the text into three sentences or less?

We have two kids together both are under two. They are the main reason I want to have a healthy relationship with their dad. And the reason I haven't abandoned him yet. 

He has always had a substance abuse problem as long as I have known him. First alcohol, then heroin, he hid his heroin addiction for a long time and has gone to rehab 4 times this last year. 

The ups and downs of having an addict in your life are exhausting. He is currently in an inpatient rehab program and has been out of the house and sober for almost a month. I've gone from hating him, to feeling neutral about him, to actually missing him a little bit every once in a while.  I've expressed that I don't really want him to move back in with us. I would rather he goes to a sober living home. Does anyone have advice on how to maintain a healthy relationship while you don't live together? He gets 2 family visits a month so there is zero physical/sexual time besides hugs. 

I had no idea how codependent I was in relationships until this last year of him being in and out of the home. I realized that I don't actually know how to have a healthy adult relationship. 

Has anyone ever reconciled with an addict? I frequent al-anon and nar-anon subs but they don't really talk a lot about relationships with the addict just how to take care of yourself. 

I would love to hear if anyone has positive stories of their loved ones over coming addiction and becoming normal functioning adults. 

I feel like I want to just be free and have a flirty fun time with a friend who likes me. But I'm not in my early twenties anymore and feel an overwhelming responsibility to make my family work.
<bot>: kids father is in recovery for heroin addiction. I'm torn between being free of addictions drama and giving our relationship one more try without living together.
