Hi Spritual living,
I have heard that waiting til the hands are starting to go below the neck/chest area is a good time to gently communicate the issue.
I myself brought it up the first day I met my guy in person. We had met at the botanical gardens....a nuetral place and I brought coffee and home baked scones. We ended up talking, etc 8 hours! By the last couple hours I gently explained that I had been very sick and that I had ended up the way I did. I put his hand over the pouch area and explained what it was and that it had saved my life. I also told him that it would be ok if he couldn't accept it. But he did:)
If a person needs space to fully comprehend and process the info, then ok. But if they really have compassion and an open heart they will accept you. If not, no problem. Best to know now. Life gets rocky and if they are bailers, be grateful to know now.
It is important to be confident in your own worth. If you value you in an authentic manner, then chances are you will attract someone who will too.
All the best.
