FWB! fuck buddies

Hi ive met this guy at work we had both got out of serious relationships cuz his girl and my husband cheated on us. Anyways. We talked and fucked and went on dates etc, we decided to be fwb,right? But damn the sex is more than great its passionate like damn yall anyways he keeps inviting me to go do things after sex and i shut him out cuz thats a rule right. Anyways he even told me that i make him want to have babies with me, im shocked anyways so last Saturday i said i wanted to fuck and he said yeah hes gon see if his roomate is there or not ,keep inmind we only fuck in the car so im like hmmm weird. He started been a dick to me and i snapped and told him hey dont talk to me like that. He told me what was wrong and said " i dont bring girls over unless its a serious relationship, so the fact that im even thinking about it is enought" like and then said he was confused. Do yall think hes getting feelings for me?.
