mr.perfect?..guys opinions preferred? ok so there was this guy and he seemed so perfect for me but not like too good to be true or anything but came closer than other guys i have been with or dated.our first date we went for coffee and we just talked alot about our pasts and what we are looking for and our moral beliefs and values etc..it seemed like we werea perfect match and i told him how am not looking to rush into dating right away though because i dont want to mess things up or do anything i will regret so to just be freinds and get to know eachother as FRIENDS first..he agreed and was soo sweet and pretty much everything i believe in he does too.we met online on a dating site and his screen name is theidealprincecharming so thats what kinda makes me feel like he was just telling me what i want to hear but at the same time he seemed so honest and sincere when we met and even just by looking at his pics he seems like a nice cool guy which is rare but yea thats what i liked.so we go on the next date 2 days later and we get in a lil arguement but he tells me how much he likes me and nvr wants to lose me which is weird but i can see it in his face he cares about me alot already and he telsl me that in relationships he is the type to give in and say sorry and fix things to avoid drama..just all these things he was telling me it seemed like he was looking forward to eventually being with me.then a day before thanksgiving we were suppose to hang out and we didnt because he was too busy with med school and he was leaving that weekend to palm springs to visit fam.i last spoke tio him on thanksgiving and thats because i approached him with a text first saying happy thanksgiving and so then we texted back and forth all night.then the next day i was expecting him to call or at least text me and he has not done so ever since then.the only thing that was weird is that he kept like telling me how much he misses me and cant wait for me to be his girl and i just got annoyed and was like "i thought i said we were gonna take things slow?" then he backed off and thats when he stopped acting like he cared anymore.was he just looking for a temporary gf to satisfy his "needs" ? and not looking for anything serious?? i i feel bad because i thought he really cared and we never even kissed or held hands since i wanted his respect
