With the Mars-Neptune square, you'll display a cold anger and bitterness, which could be qualified as ad vitam aeternam.
Sometimes, a pardon can feel like punishment. If your partner was unfaithful once, and you forgave them, that mistake can feel like a sword of Damocles hanging over your relationship. Your partner might not dare to disagree with you for fear of their error being brought up.
Even though it's not what you're looking for in love, with Mars's negative influence, you might get into some conflictual discussions. The pot calling the kettle black. But there will also be some underlying sexual tension.
When you forgive your partner, it has to be unconditional. Don't use it as a lever. Don't act like the jailer or the hangman of your relationship.
A change in situation will benefit you. You won't go so far as to through a real cocktail party, but your colleagues still might get a treat.
You used to have your head in the clouds until recently, but now you're practical and hard-working. If your investments aren't paying off, then you'll put your money elsewhere.
You'll be comfortable with yourself on two conditions: that there aren't a bunch of surprises, and that there are no arguments.
You had a falling out with someone in the past, and now you take off whenever you see them at a reunion of family or friends.
