i have no idea what to do…

so i met this wonderful guy a few months ago. hes charming, sweet, honest, a total dork (i like that in a guy :) and just over all amazing in every way. and he and i have spent almost everyday together. he likes me and i am absolutely crazy about him. the only problem is that he has a horrible ex who cheated on him for almost a year and i totally understant that he has baggage and i dont want to force him into anything that he isnt ready for, i guess it just gets frustrating..but then i feel guilty for feeling frustrated…and i know that he hates his ex and that he wants nothing to do with her, but i always have that nervous feeling in my stomach that he will get back with her. he told me that he does see our weird friendship going somewhere, but he doesnt want it to seem like hes forcing me to wait for him, but i dont mind because there is no one else i want to be with. so we are basically just two people that like each other that are physical at all…which is another frustrating situation, there is some sexual tension..that eventually might become a couple…i worry myself because i think im falling for him hard, and i dont want to like him as much as i do because i always have that looming feeling like its not going to work out and ill get my hopes dashed. its maddening…ya thats pretty much it..thank you for reading
