Is my husband a sociopath or just have tendencies?

My husband has gone to a therepist (I asked him to after finding things in his phone to another girl about sex... though he claims he didn't go through with it) She said he was a sociopath. I am having a hard time believing it because while he doesnt have a lot of love and emotion for most people. I know he loves me and my 2 children (1 of which is his step daughter). I know that he would do anything for us. He is constantly wanting love from me and the girls and always taking us out to do stuff. He buys us everything we want. He has a great job and he goes in everyday. I've seen him do good things for people. Though he wasnt raised with his sisters and says he hates them, they were hit by the joplin tornado and he went and bought her kids 300.00 in clothes because he said kids deserve to have clothes. He is all for helping his close friends out with anything. One of his friends daughters birthday was coming up and he didnt have much money so my husband gave him some. He talks to me about his childlhood. (his grandmother raised him) He watched his grandpa die and he always says he misses him and is tore up about it. He was beat up a lot by his uncles and neglected by his parents and never felt good enough for anyone... but I KNOW he loves me and my children (he absolutely adores his daughter more than anyone) and his grandmother and he would kill or be killed to save us. He does lie sometimes and manipulate and he says he has no emotions or conscience.. Everything i've read says to run from him.. but I love him so much and he has never hurt me in any way. Do I have a chance at changing his outlook on people/life if im there for him and love him unconditionall?
