<human>: Can you summarize the given text in a few sentences?

My boyfriend and I have a happy, healthy, loving relationship and have been together for 4 years. He is the person I want to spend my future with and the one who I feel is the love of my life. The friend I've known for almost as long, and we've always had a great connection. However, there has always been this romantic chemistry there that won't effing go away. A while ago, we admitted to having feelings for each other, although we never acted on it because I was in a relationship. Now, he is also happily in a relationship. But a couple of years have passed, and the feelings are still there.

I've thought this over plenty, and I haven't ever felt that there is anything wrong in my relationship, in fact I'm incredibly happy in it, and if I had to choose between the two, I'd pick my boyfriend. So it's not so much a matter of picking someone, it's coping with these lingering feelings and wondering how normal it is. I almost feel as if this friend and I connect so easily that us being around each other is like two magnets attracting… it's inevitable (that is a really stupid analogy but the best I can think of lol). The best thing would probably be to stop talking to him altogether. Unfortunately, he is also friends with my boyfriend and we have mutual friends, so that makes it impossible. 

So, has anybody even remotely been through something similar? Or if not, some encouragement or words of advice would be great...
<bot>: I have strong feelings for a good friend that will not go away, even though I'm happily in a long term relationship.
