We all have our ups and downs in life, and sometimes even though we may get something better than what we had previously we should never settle for 'in the middle' always try to aim high! In this case being relationships, which is always about working as a team but it takes the best person in a relationship to confess when they are doing something that hinders it.
Personally forget about the Xbox One, Xbox 360 still has a few years left in it and its quite clear from what you have said that you spend all your time looking after your little ones which is always more important.
Hopefully I will have some kids someday, I would love to have my own that can pull me away from the current boredom aspect of gaming and its expense lol.
Ill be keeping my 360 and will be getting the PS4, fed up with Microshaft and their stupidity but I could rant all day about how buying another Xbox is a fools choice.
