A guy is worth waiting for is he has an intact self-esteem, is happy, is mature, loyal, honest, able to cope with life's rough times.
Otherwise, he is NOT worth waiting for.
Depression is self-caused and most people do NOT "fix" themselves. Even with therapy, even with years of effort. And if they don't, then they will never be happy long-term with you, nor will you be happy long-term with them.
This person has mental habits that make him unhappy, and if he were to get together with you, once the infatuation phase died out, he would become unhappy with YOU, too.
We never end up happier, long-term, with someone than we were happy beforehand.
Getting together with him would be like buying a 3-legged racehorse.
Sure, be his friend. He can use a friend.
But keep your romantic-heart OUT of it ... and if you cannot do this, walk away from the friendship.
Don't get yourself into something that will NOT work out.
As for needing a break .. read the handwriting on the wall.
Couples who CAN make it work do NOT take breaks .. they work as a team and resolve whatever the issue is.
Of ALL the indicators for relationship failure, breaking up/taking a break is THE NUMBER ONE indicator that this is NOT a relationship that can last.
No, honey, he cannot lean on you for support.
We cannot change anyone except ourselves.
HE is not working with HIS emotions, and YOU cannot reach in and re-wire his brain for him.
And by offering support and hope you are actually rewarding/reinforcing his depression. You want to make him indebted to you by offering support and hope . .that is NOT a healthy thing to do.
Relationships work only when neither person needs support or hope .. both are whole and strong inside. Of course things happen in life . .you get fired from your dream job, a loved parent dies, you miscarry a wanted fetus .. etc. THAT is when you give each other support and hope.
But NOT just because the home life is rough.
