I added a mutual friend on Instagram, I've never had a conversation with this guy but I think he's cute. After he added me back he would send quick responses to my ig stories even though I didn't respond. Then he sent me a fb request. Every now and then we'll send short replies through dms, nothing serious. Recently my papa died and he gave his condolences which I thought was sweet coming from a guy I've never spoke to in person. So is he gradually making a move/flirting on ig or just being friendly.
