Devastated

Dear Mocha,

After Christmas I was cleaning. I found a present. I was excited when I found a diamond tennis bracelet, because my boyfriend had already done so much for myself and our 3 children.
My heart stopped and my world collapsed when I read the attached card.
It was addressed to someone else. It spoke of his undying love for this woman he's been seeing for the past 5yrs. (We have been together for 7.) The card says that he is sorry that they can't be together the way he wants due to his "situation".
I can't stop crying. I thought we were happy. There was no indication that anything was wrong. He comes home every night. He takes care of me financially, physically, and mentally.
I work and take care of he and our children. I'm devastated. We have 3 kids. We have a house and 2 cars. He makes way more than I do.
I don't know what to do. Do I leave or do I stay? How could he be laying with me every night and loving someone else?
He'll be home from work in a few hours. I don't know what to do.
Please help.

Dear Devastated,
My heart aches for you. There's no pill harder to swallow than thinking u are taking care of home and giving your all but your man STILL cheats.
There are so many different angles and questions to be answered.
I wonder why would he leave it in the house where you could find it? If this relationship has been going on 5yrs w/o your  knowledge, he has been careful. Did he leave this bracelet where u could find it, on purpose? Perhaps he wants to end it but can't bring himself to do so, so he left that for you to see so that YOU could break it off.
Or he expects you to flip so he can reverse it turn it into a trust thing, accuse you of snooping and say it's over.
The reality is, you have two choices, you can leave or you can stay.
You need to take your time and think about this from every angle. Don't make any decisions while you're so upset.
Is cheating your "deal breaker".
Are you ready to move on with your life without him?
I notice you mentioned the financial aspect but you never said that you love him. Do you? Or are you just comfortable?
If you stay, will you be able to forgive him? I can't tell you if you shld leave or stay but I will say, talk to him. Figure it out together. Whether you decide to leave or to stay, no one can judge you for the decisions you make for your family.
