My Dilemma

So I have been with my boyfriend for not even a month yet and I allready feel like it's going to end, and it makes me very sad. i dont know if I'm just too paranoid or too impatient....i dont know how I should be feeling. But here is my issue....things seem to be going fine, he spend the night at my house almost everynight....that should mean he likes me right? Well I keep comparing our relationship to the one he used to have with his ex. I know I shouldnt be doing that but I cant help it. When they first started going out he was in love with her instantly....he wanted the whole world to know that they were together. He posted on facebook that he was in a relationship with her, even edited his interests to her and all that...they always wrote on eachothers wall how much they loved eachother and he would tell her she was beautiful all the time. They would hold hands in public, kiss and things like that. They were very happy and very in love and he called her the love of his life. Well now that he is with me he is not like that at all. He doesnt want to change his status on facebook....it's almost like he doesnt want anyone to know we're together....he never writes on my wall.....he never compliments me in real life.....he never holds my hand or kisses me in public. I understand he is not in love with me yet....but if he likes me a lot, shouldnt he want to be close to me? shouldnt he want to hold my hand and kiss me and compliment me and do all those things? I'm not saying he has to tell me he loves me or call me the love of his life....all i want is for him to show me a little bit of affection. Sometimes it feels like we're just friends hanging out....and I want it to feel like more then that considering the fact that we are more then that. I know I love him and he is not at the same stage as me....but I dont think it's too much of me to ask that he just shows me that he at least likes me. i dont want to be strung a long and if the only reason he is with me is so that he is not alone, if he is just using me right now then that's just cruel. it allready breaks my heart to think its not gonna work out. And i know you might be wondering why I dont just end it with him since I'm not really that happy with him....but like I said....I love him. And every day I hope things change and he falls in love with me. I know there will eventually come a breaking point....either I confront him or he breaks up with me....or maybe, just maybe, I'm overthinking everything and things will work out and be wonderful in the end.
