At home mom & we have nothing to say anymore

I'm a 36yrold married women with 4 kids from 2 to 10 .I am a stay at home mom because I have no choice but to be with my husband being a truck driver . He is barley ever home, 2 weekends a mth if that. We almost divorced around May.I had filed. He was so distant & nasty for mths I gave him space when he wouldnt talk to me about what was bothering him. Figuring he was just going through something on his own & I didnt want to push .But after mths of this & than he had stopped coming home altogether .Always a new excuse why he couldnt make it home. Than finally I decided to look through our phone records only to find out he was having conversations with another women for 4 mths for hours all through the days & nights. WE broke up I filed for divorce,than had to try to find out how to restart with no job no money & 4 kids completely heart broken. Well after a couple mths he made his way back to us pleading to come back to us. I let him & chose to forgive. He insisted they never slept together just hung out a couple times & talked on the phone. But either way He screwed up & hurt me whether or not they did.But we have since moved & he started a new Job, different company that he was suppose to be home more. IT was working for a little while . WE where doing awesome so happy. But he isn't around much again & we have nothing to talk about when we talk on the phone. I have had that chic in my head like crazy,I keep thinking what did they talk about for hrs! How could he do that to me. I feel a lot of resentment lately. & Don't know how to deal with it .I chose to move on & be with my husband . BUt I don't know how to deal with him being away & we have nothing to say to each other. I don't get out of the house except for the grocery store or kids school or kids docs ,Nothing amazing to say there. What do I do? I feel so lost :(..
