To ignore this invitation... (inlaw related)

[NachoAddict]

I have had lots of issues in the past with my inlaws starting when I was pregnant, we fell out for a few months but made up to keep dp happy, things went well for a while and then we fell out agin. That was in July and I havent seen or spoken to them since. Dp still goes occassionally but only to pick up or drop off dsd. We fell out because basically MIL told me to "take my fucking kids and fuck off". I have done exactly that.

Now SIL has asked DP to take the children, all three, round for her sons birthday party. She lives with MIL. I have said absolutley no way will ANY of the children be going. Dp said I am being spiteful, controlling, nasty and using the baby as a weapon against his mum.

Am I really being unreasonable???

I think its something you need to work on, but that you should get a proper apology first of all from your MIL and your SIL. I would say that you are prepared to forgive them as long as their apologies are sincere. Until that time comes you wont be able to forgive what they said to you the last time you saw them.
