Who is more compatible with Mr. Aqua?? i dont know how to do all the signs and stuff so i figured i should come here for some great advice. Me and Aquarius have been seeing each other off and on the last 7 years, and I do care for him alot more than I should.. But, I really need to break it off and for some ODD reason, we BOTH cannot walk away from each other and it is getting ridiculous... we are friends and always have been ..but more FWB.. he has been with the Aries for 12 years, and they do have kids.. I also, am with someone else for 15 years now, a Virgo Sept 1st... and I really just need to let go of AQUA and it is not happening.. he tells me he cares, and loves me and doesnt know what to do as well.. and only reason why he sticks around with Aries is beucaese of the kids.. and I think I am with my Virgo for the same reasons... I dont know what to do anymore.. it is getting to deep with Aqua and I need to walk away, me being a Gemini, hard headed cant seem to let go and neither can he... Can someone tell me our compatibility and where we stand?? please help thanks

let me also add that Aqua has never been with anyone for 12 years but Aries, until I came along... and even though he has responsibilities, i do too.. he isnt the aqua man that everyone says he is.. he is not detached at all maybe his moon sign plays alot of factor.. he calls and texts whenever i call and texts back, he never good aloof on me.. he tells me all about his family, and everything else, we can talk for hours. i believe i already passed the aqua test.. we are best friends, but also lovers in some way.. it is like we have the same outlook/views in life... i think this aqua being that hes 38 years old, has evolved...he doesnt pplay games and very open.. he wants to leave his girl (aries) but is bound to stay because of the kids.. and said, that his mom raised him and his brother alone when his dad walked away... and that is the only reason why he is with her other than that, had he met me first he would have walked away already... I am with someone else too 15 years with kids, (Virgo) i love him as well, but we are totally not compatible all of a sudden... Aqua always tells me he cares and loves me and is protective of me.. I never tell him that sometimes i do because I dont like feeling emotional being a gemini myself, and we do not cloud each other.. we value our freedom, and we have a good time...all the time.. he is the opposite, it seems like than most aqua man i know.... he doesnt pull the disappearing act on me, and i am honest with him with my feelings, and he loves to hear it.... i need help.. i need to cut it off.. i dont know how.. there is something there, and everytime were togther the sparks are strong and you can see it....
