DH and I have been married a long time and have 3 young DC - we have been going through a rough patch for a number of years now. Have been on the verge of splitting up many times. Recently he suggested opening up our marriage - I wasn't at all sure and asked him what would happen if I met a man I had feelings for - he replied that it would be great! He would be happy for me. Then we (me and theoretical new man) could eventually be together properly when the children are older. I was open mouthed with shock.
AIBU (wrong topic but this seems the right phrase!) to think this means DH doesn't want to be with me at all, except for convenience for the DC. When I questioned him about it (several times) he stood by it. Said he doesn't love me in a 'possessive way'. But he doesn't seem to love/want me at all, not really.
