I'm the MOG for my son's May wedding. His father and I divorced when my son was a toddler and hadn't really spoken in years until the engagement. I raised my son essentially without his help, interest or money. I had assumed I'd host the rehearsal dinner but lo and behold he wants to. He hasn't approached me about cohosting with him and I'm not going to bring it up. My son is very uncomfortable when we're all together and I want to minimize that if I can. But I would like to make a toast at the RD. Do you think it would be okay for me to ask?
