I am glad Matt let his feelings out, but sorry it was delayed and they came out in a hurtful fashion.
Poor Si! She has a lot to deal with. Very long term relationship with one, long friendship, short romantic/sexual relationship with the other, 2 households, love and investment in the children.
Your lives are so complicated. All in the medical field, working long hours in the same hospital, business trips for conferences, a preschooler and nursing teething baby, a nanny, 2 homes... You're obviously wealthy-- gated community, 4 guest rooms, but jeez, money don't buy happiness or automatic good communication skills.
In poly, the first rule is communicate, communicate, communicate. Be fearless about stating your needs. Especially now, with 2 noisy demanding children in the mix, clarity between the adults is KEY.
Sometimes dads can get resentful of the attention 2 young children need from the breastfeeding mom. Add in mom's gf and things are even more tricky.
Good luck with counseling!
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
