This two-year transit wouldn't be a good time to make a commitment to anyone, even if they're really special to you. Bide your time, because the relationship could turn out to be quite different from what you expected. You've just entered your forties, and you're probably questioning lots of things in your life, first and foremost, whether you're on the right path.
Your love life is a huge part of that path, because you don't want to grow old alone. But at the same time, you're misreading people and situations during this period, so you're not in the best space for finding the love of your life and committing to them. So why not just try to have a good time meeting different people and getting to know them, and see what unfolds? That would be a much better idea than making a bad decision or suddenly deciding that you need to make big changes in your love life, not realizing that really, things are fine; you're just in a period of insecurity. Things will come clear to you later, and your path will crystallize. For now, all you're supposed to do is take a closer look at yourself, your needs and your goals in love; but don't try to come to any particular conclusion.
