is it possible to love your best friend?

ive known this girl, we'll call her michelle, for over 4 years now and during the 4 years we've been there for each other and everything. we went out last year and it ended pretty bad (although it did last a good 7 months) because i was still emotionally drained from my last relationship with angela*. i know she has been talking to one of my other friend, we'll call him mike, a lot lately and i think that she might like him. On the other hand, mike likes another girl from my school, even though he still flirts with my best friend. and lately, i've been with her everyday of the week and the feelings ive felt for her before are starting to grow again.

I dont know if you guys read my other post, but since my other relationship i couldnt even force myself to like someone again. and to make my decision even easier, *angela is completly different from who she was before and is a complelty different person to me.
Now I feel as if me and michelle were meant to be, because no matter what happens we always end up in each other company. I think im falling for her again but I'm pretty sure shes still has a grudge on me for breaking up with her this summer.

what should i do?

 

That might be hard to rekindle. Women tend to hold grudges over being dumped, why did it end so badly? More infortmation in this case I think would be best.

 

oh well its actually in another post, but its a pretty long read but just to summarize.
when i was going out with her i still had feelings for my other ex and i just couldnt let go, and eventually i started to regret that i ever started this relationship
