Should i give this guy a second chance or is he just using me for sex?

sorry just wanted to add a few more details so you can make a better judgement :). i met this guy through a friend and we have met a few times on nights out. we have kissed a few times at the end of a few nights out too. we were both a bit drunk and ended up spending the night together once. he sends me messages asking me am i going out but whenever im out he ignores me sometimes. he sent me a text message one day asking me when is he going to get 'another kiss' and asking me if i wanted to 'meet up for fun or go for a drive' with him and told me we can sleep together again some other time if im interested. i met him recently and he never spoke to me. he stood talking to my guy friend and completely blanked me and then i just walked away because i didnt want to make little of myself by standing there and waiting for him to chat to me. he's a police man i know its not important but you would think a guy in a job and position like that would know how to treat a girl better. but all i seem to meet lately are guys that just want to sleep with me. they don't seem to want a relationship which is what i want right now. and a few months ago he removed me from his friends list on facebook. i sent him a text message when i noticed it asking him is there a problem and he never respond back. i felt very used. i was out last friday and bumped into him again. i just looked at him and walked by i never bothered to stop and talk. i sent him an angry text message when i left the nightclub and this time he responded back. he said he 'regretted falling out' with me and told me it was over his friend (who is also my friend and he likes me a lot). why would he fall out with me over his friend? it makes no sense he just said 'it was too weird' for him. he text me telling me he thinks im 'hot, plus tight'. he wants to meet up with me again and basically have sex. he text and said 'we should f**k again'. should i meet up with him? i kind of fancy him and i cant stay mad at him even though ive tried to. i kind of want to see him again but he is stationed and lives outside of my town for most of the week. he wants me to travel up to him. so its hasn't happened yet. i just seem to let guys use me all the time and it cant be good for my confidence or self esteem. i just think at times afterwards they might change there minds and want a relationship :/
