I agree completely with Waybread, who has seen many synastry charts. People are more than charts and can hurt you even if you have enviable synastry with them, or not as the case may be. People are also subject to change, including you, and the most comfortable and easy relationship can become a snooze fest which prevents one from evolving to their full potential in the long term. This is not astrology snobbery. Take our advice: stop passing the buck, the responsibility of an adult relationship rests only with the people involved. It is best to not rush into a decision if you are unsure.
P.s., And if you cant trust someone, there is no reason to continue. If you have unfounded trust issues, then you could look into those. Usually, there are no guarantees in life.
