Help i think I made a huge mistake. did I?

[wreeek]

so i was with my boyfriend for a yr and half and he just recently told me that he wants kids and marriage but not until like 5-7 yrs down the line he is 26 i am 28 and i freaked out and figured he wasnt serious about me and so be began fighting alot and up until two days ago we were on the rocks and finally he started going out with his friends a lot not spending anytime with me and now its finally over and i guess it was mutual and then he goes and blocks me on his facebook why i dont know. im so heartbroken how he could just act like he doesnt care like this i figure he doesnt really care anymore and my heart is breaking i wish i could be with him and i cant see myself with anybody but him even thinking about being with another guy makes me ill. I dont know what tod o i have been see my friends a lot. i just wished he cared at least a little. Idk what i want out of this i guess just some support. i can't see myself ever getting over him.
