Lil help please 😊

Okay so there is this guy who everyone I spend time with (like my two of my sisters, and my good friend) don't like him much. In my opinion he can be a dick sometimes but at the same time when we talk he's really cute and funny. We've been really touchy feely lately and I haven't stopped him because I want it to happen, but at the same time I don't want to be with someone my sister absolutely despises. I want to get the nerve to ask him to be my FWB or my BF but when the opportunity comes all I can think about is pouncing. 🐯

Another issue is I don't know what my mom would think. Him and I both have the same interests and everything and my mom doesn't NOT like him and she told me that if I want to date him just ask him but I feel she really doesn't want that.

What are your opinions on this little situation?
