In it, you are spinning a bit. It happens.It's best not to make any major decisions while you are.
Can you find something to do later or someone to talk to?
Listen, I know this is so hard. And having young children and being pregnant makes it 100 times harder.
I understand all the things you want to say to her and to him. I do. But I can promise you this, it may make you feel better for a moment, but, it will not get you the results you want.
If anything, it will move them closer together. They will become a team against you.
It will be, see Init, she didnt listen to me. In his mind, it will validate whatever it is he has imagined is the problem with you.
This affair will not last. They rarely do. How can they? Look how they started? He is married and broken, she is an ow.
But that doesnt really matter right now. You have to decide if you can outlast it? You have to decide if you can do this, sweetie.
It is ok if you cant.
But if you think you want to try, then you have got to stop questioning him, looking up his google history, etc. That stuff doesnt serve you well.
You have to live your life as if he isnt going to be in it.
Let him blow in the wind right now. This is his journey and he has to figure it out on his own. Because the more you interfere with it, the longer it will take him to do that.
Become the best you. For you and your children. And if he ever looks to you in the future and you want him, he will see a woman of courage and strength.
