I'm confused

my boyfriend and I have been dating for 5 months! at first he was nuts about me although I'm a tomboy and I never act girlish! he loves the way I look but recently he's been acting strange and saying I don't care about his feelings although he does! it is true because I take him for granted someties and he says if I love him I should grow up a lil and start acting like a grown up!! and he says all love really means to me is sweet talk and that's crap!!! help??? I hurt him emotionally and he's like I have to see if I can get over the hurt u've caused me(that is never listening to him always doing what I want and ignoring him) I love him to death really I've never luved anyone as much!!! can I get him back

im sorry it sounds like he is cheating on you or he just want some ass if you not giving it o him then he found it some were else
