Believe me I know exactly how you feel. It is difficult to stay optimistic isn't it. Here's what helps me though...you mentioned your wives love languages....well how does she show her love towards you currently?
See...I learned to recognize the different ways my husband displays his love for me and that helps me when I get down, if I can recognize them at the time. When I can't though, or when I just get too distraught over the entire situation and find it difficult to HOM I try to channel that into something more positive. Sort of like what I posted in a new post this morning "New Discoveries..."
It's times like this when I realllllly need to be able to have an open/honest discussion with my H. Are you and your wife at a point yet where you feel you can do that...or do you feel she shuts you out?
