Long term relationships..

I’ve been with my Fiancé for 9 years we have 2 kids..this year we was suppose to go ahead and start planning our wedding but lately we have been having problems. He’s been with hanging out with his brothers and cousins at the bar more. He does not really text me or call me after work to let me know most of the time till I call or something. Sometimes he gets back late. I know for a fact he isn’t cheating. I just think our communication isn’t great anymore and idk what to do. We talk about it more than once already it just keeps happening..like right now I’m feeling anxious he have not called or anything yet he said he should be getting out of work about 3-4 just hoping he would come straight home
