It's been two years since this happened? Or did it just happen? Either way, she's being honest with you, so I don't think she's wanting to cheat on you. You love her, so you should stay with her and help her through this depression - go with her to doctor appointments if she needs your support and let her know that people care about her.

I've seen this one before. My exsister-in-law pulled this one twice before her husband wised up and put her out. You need to get out. The depression isn't why she cheated. It's just the excuse she's using so you won't leave her. What's going to happen the next go round? The same thing. She's already proven that she can't be trusted and has no respect for you or your relationship. Go find somebody who deserves you.

You could give her a chance if you love her. Plenty of open communication on both sides, find out why she did it and why she couldnt come to you with the problem. Deepening the communication is the way to solving any relationship problem, no matter how severe - as long as you both want to. Counselling as well could be useful for the depression, to help her deal with it and how to handle it. Id say as its a one off, give her a chance - twice then leave for your own wellbeing. Good luck.

If she was really sorry, do you really think she would be making excuses? Maybe she is telling the truth, but real apologies do NOT contain any ifs, ands, or buts that say "I'm sorry, but I'm excusing myself anyway". Here are examples of fake apologies: "I'm sorry, but it's your fault." "I'm sorry, but if you were in my shoes, wouldn't you have done the same thing?" "I'm sorry and I really just wanted to ease the pain." Here is an example of a real apology: "I'm sorry. I was stupid. I don't deserve your forgiveness. If I could take it back, I would. I was an idiot. I should have thought more about how my actions would have affected you. I shouldn't have made my needs become more important than yours. I'm really sorry. I understand if you will never forgive me." Some tears might help the apology become more believable also. These words might also help: "I deleted his number off my phone. I've cut off all the ties I have with him. I will try my hardest not to put myself in situations where I might be tempted to cheat. I've learned my lesson. You can say anything you want to me. Take as long as you need. I can't bear the thought of hurting you ever again. I deserve all of the guilt I'm feeling right now. I don't deserve you. You deserve more than me, better than me. You deserve someone who doesn't cheat. I'm sorry beyond belief." You don't have to expect a show or a fake apology, but those thoughts would probably cross the mind of someone who is truly and sincerely sorry.
