To TS,
I think i can help you in this case. Erm...not that your bf doesnt wanna share your problem with you. Sometimes it is hard for them to express their feelings. It will be easier for them to express it among male friends than female friends especially gf.

The harder you force them to share out their problem,the annoying they will be and there will be an argument.

Just let them be. When they are ready to talk,they will. Dont put pressure on them. Sometimes they can behave like a little boy and wanted to be pampered....hahaha..You can do your part here.

They will be ok. Just try to be understanding and thats all.

Hope this will help
