lost with an aries male

hey everyone

i am a libra female and i have met that amazing aries man over facebook! without saying that he was charming, comprehensive and he couldn't stop talking to me all day , really from those cute good moorning texts to goodnight texts! it's been 6 months now that we are talking but he started thinking about marriage and said that if he wanted a relationship it should end with marriage! after 3 months i told him that i love him, and things changed like he became more sweet and acted more than a friend with me and started acting like a little jealous boyfriend! anyway these 3 months he has been away too much eachtime i talk to him he doesn"t reply or say he is busy ! when i brought that i wanted a serious relationship with him he said that he cannot be with me , he cannot commit, he doesn't want to hurt me and he cannot tell his parents about a virtual person that he want to marry,he need time alone ,and after a while(a week or 10 days) he comes back again acting like nothing is wrong ! last week i talked to him about meeting in real life, and i let him choose where he want that even if he doesn't want to meet in my country, he got angry and said that he don't want to commit while i was acting exclusive and i am still and turned down everyone since i have met him! now he doesn't want to talk to me he said he needs time and he still says no to everything i ask for! i am lost with this guy i really love him and i have no intention to hurt him at all ! what should i do ?
