Is this a stupid breakup?

ok, so i was planning on going to the skatin rink with my boyfriend. i was excited cause he said he was going to kiss me...but then i found out the day b4 tht i couldnt go cause my mom already made plans..the next day, i told him and he said tht he would just hang out with his sis. then my mom said i could go if 1 of my friends dad could take me, she couldnt go so i told him. (i couldnt go for long anyway so i just decided to go wit my mom) i told him tht and i said srry he said it was OKK!! so like at 10:00 i said tht i could go next friday and tht im sorry. he said yeah.. and i said wat? he didnt answer me then i said like 10 min. ltr wat again. about 15 min. aftr tht he saud "im breaking up with you so...bye" all i said was "alrite peace" cause i cnt fight with him, hes a good arguer. so now i think hhe broke up with me cause i couldnt go. idk wat happend.
