Most Helpful Girl
Clearly he's not making any effort with you. But there may be more to this then your seeing some men are really effected mentally by losing their jobs etc. They feel it's their role to provide for to look after and protect their partners and families and being unable to do just one of them can have a big effect on their mental Well being which may be the reason he's distance himself. If it is I'd decide whether or not your prepared to support him (mentally not finacially) through this. He probably won't admit fully how he feels but if he's actively looking for work and knows your supporting him you guys may get through it.
If it's not a case of how unemployment has effected him then you are right to walk away he's clearly not invested in the relationship. The only way you can truly know though is by talking to him.
