<human>: Provide a brief overview of the text.

Sorry if I sound irrational at the moment. I'm just super worried and expecting the worst and need advice on how to ask for reassurance without sounding accusing. 

*short back story* We've been together for a year. He cheated on me but I stayed with him. He had stayed the night at her house when he cheated and I'm worried he's going to do it again. 

He's going out of town at a friends house to work on his car. His friend lives about an hour and a half or so away. 

Earlier today, he talks about how he doesn't think he'll go until tomorrow morning because he doesn't want to stay the whole weekend there. He just wanted to sleep there for Saturday night then come back Sunday. 
Later today, Friday, he says he's actually going tonight because his friend want to drink tonight. We hang out a bit for the night before he goes.
When we're saying good-bye, he mentions he requested Monday off so he can sleep in. I thought it was weird because he said he didn't even want to stay the night more than day but now he is for Friday, Saturday, Sunday and now maybe Monday? He's broke, he's been complaining about his paychecks. Why would he ask for the day off?
He says he wants to drive back late Sunday night then sleep in at home, then he'll just see me Monday.
Im freaking out about if he's really just planning to stay the night at this girl's house that he cheated on me with. 

I've recently started going to therapy for anxiety and self esteem because I get so worried sometimes. 

I need advice on how to ask for reassurance without sounding so crazy and accusing?
<bot>: I'm worried if bf is really going to stay the extra night out of town, or using the extra night to stay at a girls house.
