He thinks I'm cheating.

Hello ladies, I work two jobs and have been for years. With the holiday shopping season now here, I'm working 65 hours a week. I don't get home till around 3 am from my retail part time job. I'm now being accused of having an affair. I just don't know what to do. We've been together 3 years and I've been working two jobs 4 years. This has really thrown me for a loop. I need two jobs to pay all my bills. :(
