Boiler while I understand what you are saying, and as me being a guy who usually always tries to give advice on here that tries to use every means possible to save a LTR that is worth saving-to the point where a few call me a WK, in this case I believe that because BB is a respected poster on here, some are willing to let him slide. To me, that is a dangerous road to go down. And it goes to show that even the wiliest and mature guys on here can slide back into afcdom.
Cut out everything else. The lack of sex. The weight gain. The general boredom with each other. The lack of spark in a relationship. The fact is this girl, who lets be honest here, probably does not have a lot of other great prospects right now, left BB. Broke up with him. Moved to another place without so much as a warning. For the life of me I cannot imagine my fiance doing such a thing, as that is such a huge change and upheaval in lifestyle. So to do something like that imo really shows a lack of love from her to him-to be able to go to that extreme. Now, did he do a lot of things that caused her to become this way? Yes I am sure. It sounds as if BB became lazy, unambitious, content, and to be quite honest about it, immature. That is not a cutdown of BB, but any man his age should be able to survive on his own without relying on a woman. At the very least he should have his own things and be able to pay his own bills.
As I said a few days ago, and as Gordon Gekko said before that, this is your wake up call pal, go to work. This is a golden opp to start over, to give him the incentive to get his life on the right track, and to find someone he REALLY is proud to be with AFTER he gets things going with his own life. And not be with someone just because. BB was left by a girl who I bet 90% of guys on here, a site full of desperate men, probably would not touch. What does that tell you about his standing in society, and in her eyes, right now? Especially if he comes back groveling like a lost puppy dog as it appears he is? She is going to rule him with an iron fist. He is going to be walking on eggshells and it will never work out. They are both wasting each others time here. Instead of spending time and energy on people that do respect BB, he is going to be spending precious time and energy on a person that has shown what her true colors are.
IF this was any regular poster on here, you know exactly what you would be telling him Boiler, to leave and don't look back.
