NC because it's a bit sensitive.
Met this guy through work / clients, seemed nice, genuine, funny and warm. We went on a couple of dates, and had all the usual "tell about yourself" talk.
From a couple of dates/ events he mentioned, I realised that he divorced his ex-wife after a brief marriage for unreasonable behaviour / mental issues when their children were quite young - around 2 years (oldest) and 6 months (youngest). He seems to be a good and involved dad now, but does not have them overnight (they are 4 and 6 now).
Is it necessarily a red flag? I feel a bit uneasy about it and has been thinking about calling it a day several times already - but then start having doubts and second thoughts, I really like the guy otherwise.
