I just read one of your prior posts...in it, you indicate that your wife said she loves you but is not "in love" with you. I expect this is the real reason she's not saying it to you...

I'm hopeful that the "in love" can be rekindled, but she may think it unfair to say it to you until she really feels it. She probably won't be able to come close to feeling it until you, and she and the therapist get a handle on your depression and address why you never sought help until now, even though she asked you to...

Being around someone with depression issues is very exhausting, and she probably just feels emotionally wrung out and shut down. Honestly, I think that working through your depression in a way that helps her may mean that you have your own therapist for this purpose (in addition to marriage counseling)...She can love you and support you, but you have to fight the depression on your own. She has to see that you are facing that particular beast head on and that she's not responsible for fixing it for you or making you feel better....Being around someone with depression can be extremely stressful because you feel as if you are failing your partner...that you can't make them happy...maybe take the pressure off of her by not expecting her to say "I love you" back....Just show her you love her and give her clear space to process her own stuff right now.
