Is he trying to talk to me again?

well me and my ex broke up in December but we stopped talking in feb. cause he had a whole diff girl & he still goes out with her . its been 3 months we haven't talked and i added him on facebook we sorta talk as friends . but now he keeps liking my statues & tagging me in his pictures & i'ming me & when someone else writes me he would like it . what you think he likes me still?
