Is OTHER wrong in the post ? POST : Im (f26) cryiing right now ,sorry for my englosh (nor my native languaje)

i just broke up with my bf(m27) we been into a ldr since june and things were getting far different from the start.

i love him ,and i feel hes a perfect guy (very sweet ,respectfull ,nice taste) we share a lot of things in common the reason i wanted to break up with him is because hes in the university and working at same time but lately hes just have less less time for me and also dealing with his life ,i will never make him choose me over his school ,never , so thats why i told him that break up its the best for now.

he agree wth me, not event try to stop me , the gap between our different cultures is not too big as maybe he think, hes from pdx im from mexico. we meet i september for more than a week and things were just very cool and perfect (like if we know each other for years) but then trought the time things were changing a lot in the sense that less interest ,not sexy times (or very few) ,i really really try to just deal with that but at the end of the day i was heartbroken and sad .

we planned to make a trip to vancouver canada to meet there (cause i dont have visa) i pushed him to buy tickets with time , to catch a good deal , he pay almost all the ticket ,i just put a few cash. 

now i feel bad cause i cant cancel the ticket , i told him that i will try to send that money back .

he used to offer me to meet there as friends , but i cant see him as that ,i mean if i agree to that im pretty sure we gonna kiss each other ,fuck like bunnies  and then after the trip the moral hangover and my feelins gonna go to the trash, thats why i told him to not meet

he offer me to stay in touch in fb, i agree with ,i hope i dont start looking of what hes doing on there cause i just used to open on fb to see him , it will be weird to have his close friends there on fb , i always wanted to meet them and hang out cause they seem very cool people ,but now i have to made me the idea that ,that  will never happens :(

i really feel shitty i cant even write so well right now :( , any word ? opinion ? advice?

TL:DR i feel very sad to break up with my bf a month before we meet again
