Search Results: what do guys expect when they buy you a drink

I have fuck buddy for month and half. We met on tinder and had sex and it was really great. We talked, watched tv, had sex, he gave me massage and kissed my whole body... It was really gret night. He texted me next day and we talked and he said that he doesn't want nothing serious that he wants us to be fuck buddies and i agreed.
He went to work on coast and we texted each other and had phone sex and normal talk. He said to me few days before he got back that he didn't had sex since ours last time and i told him me too.

Few days ago we taxting (my brother figure out that we are going to have sex and told his friend) Friend screenshot me messages and I sent them to fuck buddy like "he knows where im going" and my fuck buddy only figure out of that "that im going with another guys too". he came to pick me us and we went on one private place. It was near his house and he showed me his street where he's living from his car. We had sex, kissed a lot, laugh and joke... When we were sitting on back sits of his car he took my hand and kissed few times (something like in romantic movies). I was bit confused i really didn't expect. He talked about his nights out that weekend and showed pictures and talked about when he was little and life and his friends. He stopped when he was dropping me home, to buy us drinks cause we were thirsty. When we were near my house we kissed and we agreed that he will come to my house tomorrow to have sex. Next day i texted him if he wants to come around 10pm and he didn't texted e till 9pm that he can't, he has something.

It was different all that this time. Should i've been woried that he feels or?
