Jeez foxy, one person posts about a similar siutation to yours and that is the only post you take any notice of.
Did you really gain hope from loopys post? In your situation I wouldn't have. I thought it was sad that after all her 'nudging' the relationship still wasn't where she wanted it to be and she's clearly not happy about it.
She pushed for them to move in together, then she pushed for them to have children and as soon as she purposefully stopped pushing and waited for her partner to do something ie propose.....nothing happened.
You started this thread because you were worried that you might resent your boyfriend in 15 years if he retires- don't you think you might resent him long before that if you are the only one making any effort to move your relationship along?
Don't you see that the fact you feel you have to defend your relationship is a warning sign in itself? People are only commenting based on what you have written about it (with the exception of the bizarre Daddy love post!).
TBH I am having trouble calling it a 'relationship' or calling him your 'partner' as after 2 years, you still only see him 2 nights a week ffs.
I don't know anyone who would say they are 100% happy with their relationship but people weigh up all the factors and take it from there. Based on the things you have said about your situation, it is a recipe for disaster.
Your £600k house and chlidren with him is nothing but a pipe dream. Aside from the fact that on your salaries it is a financial impossibility, it will never become a reality because HE DOESN'T WANT TO LIVE WITH YOU.
This crap about being ready in a year is nothing more than stalling tactics to keep you where he wants you. He is selling his flat which, if he wanted to live with you, would be the perfect opportunty to chose to get a place together, even if its only rented initially, when it's sold.
He's not doing that though is he? He's going to buy somewhere else ON HIS OWN, just like he will retire at 55 because HE WANTS TO. He is making big decisions about his life without you being involved because deep down he knows you wont be around and you are so busy with your head in your fantasy relationship cloud, you can't see it.
