Does anyone have some friendly relationship advice?

Married, no kids. My partner doesn’t provide me with everything I need in a partner. I tried talking to them about it, suggested counseling, and it seems they are unwilling to try to work on things.

Logically, it seems easy to say move on, no sense in not having your needs met, but I believe marriage should be permanent, and have a little fear of turning into a serial spouse.

Since the beginning of my marriage, I haven’t dealt with financial responsibility. I hand over (most of) my paycheck, the bills get paid. I found out recently that we are in a TON of debt, and I feel resentful of that. I wonder if I do end things now, how I can make ends meet.

To make things even more dramatic, I met someone else. We aren’t physically involved, but I think it could go somewhere. (I know full well that leaving one person to be with another is always a bad idea, but the notion that someone out there is as multifaceted as I am was not something I could have imagined.)

The thought of splitting up my life is terrifying. Facing the world as a divorcee is something I thought I would never do. I don’t see myself as ever going to be happy if I stay, though.

Does anyone have words of advice? I’ll take encouragement at this point, too.
