I'd be worried about this new man Pink Champers.
Some men hone in on vulnerable women - are too good to be true at first and then become manipulative.
Tyedye there is a truism - if it sounds too good to be true, it is.
You would do better by taking some time on your own with your kids to find out who you are out of a relationship - any relationship. Meet him by all means, but maybe tell him you need a few months to just enjoy life without a man around.
If he really cares about you he will understand and back off for a while - a few months at least.
I know you'll be wanting to enjoy all the things a new relationship can give you, but your and your childrens long term stability is more important - even more importent than you getting high on a new love.
