IMHO you have every right to be angry. You are in college working toward a degree and he made a mistake. If you weren't angry, I'd be worried about you.

He made his choice and made a mistake, unfortunately you are also paying for that mistake too.

Don't keep the fact that you are angry with him from him. Honesty is the basis for any good relationship that will last.

Don't keep this to yourself, do get any help you need and do tell him how much it has hurt and effected you. Depending on his response you will know where you are on his priorities now (as harsh as it sounds) as you weren't the first on his list before he made his mistake.

Been there, done that and as hard as dealing with it is, well we've been married for 27 years.

Be angry, think about you first because he didn't. If you want to work it out, confront him with your feelings and what you expect in the future.

It worked for me.
