What is furstrated?

You are confused about your relationship Does he trust you or does he stay with you because he is comfortable?

I have this boyfriend and we dated for a few months, we had a rocky point where I thought he didn't want to be with me anymore, this was after he yelled at me to get over of his house. I put back up an ad on the dating site that we met off of, after that rocky point I didn't get on the site, we left for a weekend vacation and things were fine... he found it and accused me of cheating. I tried to explain to him that what I did was irrational, but he called me names and told me to come and get my stuff out of his house. I didn't get my stuff cause it hurt so bad that he sat there and called me names. 3 weeks later I receive a text message from him saying that he "was sorry for what he did and that i am a beauitful person, I was just furstrated with the situation and didn't know what to do" So he told me he wanted to talk, we went over there talked, did some stuff(you should know what this means) and then he left for Hawaii, texted me while he was there told me he missed me wished I was there with him. I picked him up from the airport Sunday and he was excited to see me. He made a comment when we got back to his house, that I should get a tattoo of his name on me to show that I cared. I asked him "what? Why?" and he said "I don't know pretty scandolous" I was thinking in my head well if you think that then why are you trying to be with me? Monday night went back over there, was really uncomfortable because his friends were there and I don;t know what he has said to any of them about me. I stepped outside 20 minutes later he came outside and asked what I was doing and I said on the phone and I went back inside with him and sat on this chair that was across the room, he looked at me in odd of why I wasn't sitting with him. He then got all lovely dovey when people started to leave. And the next day i went back over, he didn't great me at the door cause he was watching a movie and sports on the TV. Yesterday my brother got him dog bones for his new dog and I told him that I would be over between 7 or 8pm after I was done with my essay cause i would need a break. He said "Is that what you want to do?" I said "I don't care." at the end of the conversation I told him I would come over the next day to drop off the dog bones and to have him text me after his lunch today and if he wanted to before he goes to bed to text me. No text after bed and haven't received on yet today. I think I'm overanalyzing everything, but im afraid to talk to him cause I don't want to get him up...I do care about him, but things seems a little different. Maybe I'm just being overbarring or something. Advice please? And sorry this was so much to right!
