Ok... my grandfather absolutely loves my ex (long story) and he had his one project car stored in my grandparents barn. When he left my g'parent's place from picking it up he called to see what I was doing for easter... I told him that I would be making a small dinner for me and owen (my son). I said why are you asking...why you want to come over for dinner. He said yeah maybe. (Believe you me that nothing is going to happen)

but the question is would you let an ex come over for a holiday dinner?

no

oh yeah i'd fix him up something real special

To be around the kids, yes. To try anything with you, no. But then again you have just as much control over that as he does.

depends how the relationship ended and if he was bringin the pie

im talkin bout humble pie for those that are slow

That's totally up to you. It's an individual situation. Maybe he want's to spend it with you because it mean's something to him.

hmmm..he if brings good desert....

depends..

my ex has been in my home at different times..

after awhile he would wear out his welcome...

so I would have to nicely tell him to go...

Those days are over..thankfully...

I let him in for my sons...

For the childs sake by all means, if both can be adults about it

depends on which ex, lol.

pretty close with most of them.

Ex-wife and I share a son, so she's welcome to come over (I'll probably just drink heavily).

Ex-girlfriend, however, is another matter......

No. F*ck No.

Seems like you two left on good terms and are still friends, why not? As long as they know nothing is going to go beyond friendship.

Why not? You are in control of what happens, all you have to do is say NO if he wants things to go to far. Is this for you or your son? If you want him to come over then let him come over. I see nothing wrong with having dinner with your ex. BUT don't confuse your son IF that is his father.
Children automatically want their parents back together, so he might think you guys are working things out. I wouldn't allow any kind of "friendly stuff" to happen. It would strictly be just dinner. I think people do things in front of the children then later on regret it.

for holiday sex
no one likes to really be alone for holidays

Depending how the break-up was and if we were still friends.

I say why not. Just because you two did not see eye to eye on the relationship there is no reason to fight. Let the child see that two people can get along after a break up. it will be good for the kid. I wish me and my ex could get along like that.. I wish you best of luck.. if nothing else kill him with kindness
