Confused - Is my trucking boyfriend cheating or frustrated?

My boyfriend and I have not been together long even though we moved in together not long into the relationship. He is a over the road driver and I am a stay at home mom.

Recently he had a heart attack and spent almost a week in the hospital. I stayed with him, except for the trips from hospital to hospital, the whole time. It put us back financially almost 2000 dollars.

So we have been having money problems, but we don't fight about it because that's not why im with him so it doesn't bother me.
However, because of it he recently had to turn in the truck that he had leased and go back to being a company driver.

Ever since he started driving company he has not wanted to talk as much as we used to and when we do has rather short tempered and in my opinion secretive.

For example, yesterday we talked for about half an hour in the morning and then he saied he would call me when he started driving last night. Around 830 i got a message saying that he was going to bed and that he had to start driving at 2am.

He had originally told me that he was driving at 11pm. He said he was alseep all day, even though he had slept all night the night before. Then tonight he said he had to drive around 1-2 am but when I asked if he would call me he said that it was to late to call. I told him that I didn't have to get up early so it was ok but then he said that he didn't even know if he would be driving.

Im worried that he is either frustrated and having second thoughts about us or he is cheating on me. Please help, my kids and I really love him.
