My SO& I have been together 3 years. He has 1 daughter from a previous relationship. BM is a mess,pure drama, In and out if rehab, from man to man, and SO has primary custody. He didn't tell his daughter he was in a relationship for at least a yr and continued to keep contact between the two of us at a minimal until the last yr maybe. We've all started doing more things together because I finally told him I thought we needed time together to bond. I wouldn't say we've bonded much.
