I don't know what to do with myself.

This has been the hardest time of my life. It really gets to me knowing a random woman had more respect for me than the man that I was with for so long. The father of my child. This random woman had more respect for my daughter and I than my own husband did. I'm a wreck. I'm trying to hold myself together. He's still denying it was him but it was tinder. It links to your Facebook. I know how he acts and talks. I know it was him. He's in Manitoba right now and I'm in B.C. he's gone for work til next weekend. Then he comes home. I'm trying to keep myself together for the sake of my daughter but it's hard. I've been having a very hard time sleeping or getting out of bed. I barely way and I don't want to do anything. I start cleaning house and I just want to sit on the floor and cry instead. I've done nothing but love that man. I stood by his side through everything. His mother wants to rip him to shreds. His family knows how I've been to him. His sister didn't believe he would do such a thing until I sent her the messages. I feel bad that she had to see her baby brother in that light but I couldn't handle the questions on if it was him or not. I'm dying inside. ??
