if my ex calls me???

if my ex calls me sometimes. and talks to me at school on the bus alot, and he looks at me sometimes in the hall way but i never stop to talk to him , but he calls sometimes, and once he said he liked me and only says he doesent to make me mad, then like last week he called and said ya i met a girl and i might go out with her cause there isent any good looking girls at our school and i need someone who gives me responsable,respectable,peaceful, and safe, what did he mean by that, and + some boy on the bus kept asking kevin if he liked me, he dident answer, he just said she was on my top 3 before i dated her, whats that mean, then the next day he told that boy that im wanting to sleep with him, its going around school, some boy told him, and kevin knows i like him,,,, but why would and ex bf talk to his ex gf, i mean were close now, he broke up with me about 9 months ago, and he talks me to. calls me, does he like me? but
