I think the 'in love' thing is you being in love with the idea of being loved and in love.
Many of us have had that, and it's the stufff that damages our lives and those of our kids.
We are not in the middle of your relationship, with the whirling emotions and addicitive rush of it all, we can see that the clues are there to some very serious potential issues, that you are so hellbent on having a love affair that you are throwing all caution to the wind.
to a different extent, so probably is he.
NEITHER of you are in a healthy place and ready for a relationship given your histories.
That, as I have said, is OK if only you and he get hurt (but it can be avoided) but your DC have no options.
ADD to this the fact that our DC learn from OUR relationships and really, you know that there are too many red flags there for you to carry on as you are. You do need to stop, think and take things WAY slower.
The other thing is, as much as it's easier for the kids to get all piled in together in terms or childcare, far too soon for a young couple getting to know one another to have to get all stuck in the rut of 'blended family'
being an adult, enjoying a man + woman relationship, being selfish about it and keeping it to yourselves is something so precious, and so important.
put it this way, you'd understand if I said to you that meeting a guy on line and getting PG in the first few dates was probably not wise. You don't know him, he could be anyone.
What you and he have done in getting all the kids together in a matter of weeks is actually worse, in so far as if you were PG, you'd have a good 8-9 months to spend just you and him together.
I'm sorry for looking you up, but it really was relevant to see where you were coming from and i suspected that there were bigger issues as the bigger picture than you were admitting to.
I think you are beginning to see where we are coming from, the first step to this is to admit that you do have issues that ought to be looked at. By investing this time and love in yourself, I promise that you will be healthier, happier and stronger in future. Your DC will be too.
