"I usually only see d15 for 15 minutes a day, at dinner, as she is then upstairs with W (and I am down), but would love to see her more, though without demanding or forcing this in any way. "
You're not "forcing" your way into anything if you just go upstairs. You've gone backwards again. You're afraid to spend time with them. Just do it. No analyzing, no fear. Just walk up the stairs. Maybe you could have some dessert and just go up and offer it to them then hang around. Just do it.
THIS^^^^....Read this post again, seriously...AND get time with your d. Just Stop waiting for an invite. You are her dad. You think an invite would mean that you are guaranteed no rejection.
Stop waiting, and gird yourself for the risk you are taking but take it anyhow. Otherwise you'll be downstairs "waiting" for another 10 years. Maybe you'll then wait to get an invite to see the grandchildren? THINK out the implications of your inaction.
LL, all this advice has to sink in now, or I'm not sure it ever will.
Please, please hear me.
