I went out with a gut who had known my husband longer than he'd known me. It worked for about 6 months and my ex was OK with it. It was a bit strange to go out in a group of friends when they were both there. And when we started going out we didnt tell any of the others, just my ex, when my guy was chatting to exes best friend about bringing 'redcrx' to party, the other friend said 'what A's redcrx?' and he said 'no my redcrx' which caused a few shocked faces lol
its even stranger when i go out with the gang now and have my partner in tow. They joke about me having been out with the whole table, not quite true lol
