We are seeing each other however he said he doesn’t want serious relationship and we see each other exclusively he says . But he acts like my boyfriend, we both affectionate , caring, respectful etc and we message each other all day long . I am confused but he seems to be giving me what I need as in he acts like a boyfriend but as he works 12 hour days he find hard to commit to relationship however he acts like a boyfriend so I’m not seeing anything different . The words he says “your mine” , shows he is possessive but he is not at all. 

Well I asked him yesterday about what he said that night saying to me “ you”re mine” and he said that he does get obsessive.  
We had sex prior to the conversation about it and he didn’t say anything at all . 



 

I am dating a guy only 2 dates and we had sex for the first time last night however while having sex he says “you are mine” . He said it 3 times last night while having sex. We did more sex during the night and again he said it.

what does this mean? Or is it just a fetish?
