Being a stay at home dad and not bringing home the bacon is hard for a lot of men to handle. It can be hard for women, making it hard for women to respect and be attracted to their husbands. Some couples pull it off, but I think it goes against some people's 'wiring.' I realize you are in school. A husband being in school can have the same issue. If she's providing financially and he isn't, it can do a number on her brain and feelings.
If I were you, I'd try to get her to pray with me regularly and follow the example of Christ like Ephesians 5 says of washing her with the water of the word. See if she will join in family devotions.
Being a bit firm with her about going out and leaving the kids might help, too. If you are the type to acquiesce and let her make decisions, standing up for yourself a bit more might help her attraction to you.
If I were you, I'd also paint for her a picture of her future life, fat on her third marriage wishing she hadn't thrown the first away. She'll probably get a lower quality man, a man not wise enough to stay away from a woman who doesn't believe in marriage. She'll probably find plenty of men willing to have sex with her, if something like that isn't already behind her motivation to leave you. But it's pretty dumb to marry a woman who has low commitment to marriage, especially in a society where the judge is likely to give her half.
You could also ask her who she is having an affair with and tell her not to hide it anymore. She might let a little trickle of truth out and add to it over time, if that's what is behind this. You might want a little evidence first. If the cell phone is in both of your names, you may be able to get a record of calls. It could just be her not being attracted to you since she's working and you aren't combined with accepting the thinking of this world, though.
