Do you think most guys would cheat in this situation?

So my friend is in a long distance relationship. They were together 4 months when they decided to go long distance to study. Its been 3 and a half years and they are still long distance and they have only seen eachother 3 times in 3 and a half years. But they plan to move in together next month... I am just worried for her as I just dont feel like her guy would be loyal for that long especially considering they have only seen eachother 3 times for a few days. Im worried she might get hurt and I think there is a strong chance her guy may be cheating. She says she doesn't care what he does and that theyre relationship will start properly when they are living together. What do you think about her attitude and the situation? I just dont want her to get hurt.
