Touchy situation

So my ex boyfriend was a Gemini, we were on and off obviously for a long time, then his best friend being the kind cancer has been there for me through all of these ups and downs. Slowly we have become very close and now it has gotten to us making out and stuff, haven't let it go farther because I don't want to cause problems between friends but I enjoy the comfort he brings. I want us to stay kind of friends with benefits but I'm scared the cancer will catch feelings and want more? I don't know how he feels for sure because he said he has thought he had feelings at certain times in the past and I told him I had the same but I don't feel that way right now. Should I cut it off to protect his feelings if he does get attached?

You'll have to keep the lines of communication open. If you want a friends with benefits relationship, make it very clear to him so he knows exactly how you feel and what you want out of this. If he wants more after understanding your feelings, then you might want to think consider your next plan of attack (i.e. cutting your losses or developing feelings yourself!)

Well if you knew how fucked up my Gemini ex was you wouldn't blame me. It was very toxic and still he tries to come back and talk to me when he's drunk/sad but then is hooking up with random girls. He says he will always love me he just can't be in a relationship rn. Aka he wants his cake and to eat it too. I'm trying to move on because it's been over a year of this back and forth shit. So yea I kind of went straight to the closest person when all of this was happening. I'm not saying I'm doing the right thing, but its better than going back into a toxic mess. I could catch feelings I'm not really sure, I've tried to block that out, but the closer we get the more I feel connected to him anyway. It's almost like I've been hurt over and over by my ex and now I have this guy who I know is loyal and might actually treat me right so I don't want to let that go. But then I'm also sometimes not emotionally available to him because I still have some feelings for my ex. It's very confusing but I really do not want to hurt my friend. I care more about him getting hurt if he catches feelings. I don't want to selfishly keep him for comfort if I think that he will expect more. He is so sweet and caring I couldn't do that to him.
