Hi I just met someone via social media but I'm not sure to trust him. L7 saturn,his ruler, retrograde and in his 12th house, is he hiding something being secretive? Also my 5th and his 5th ruler opposing, jupiter conjunct moon L1 weak in scorpio.
My concern is that he is mostly interested in himself and not you. Using whole sign houses, he/Sat/L7 is in his own house, strong in his dignity. You as Moon are distressed, in your fall in Scorpio. And he/Sat is in the sign of your detriment, so more distress is added to the atmosphere.
While you as Moon do apply to him/Sat by sextile as he approaches you by retrogradation, which does suggest opportunity, I do not see this as a promising or comfortable relationship for you if you want someone who directed his interest toward you.
Whether you can trust him or not, I suppose it depends upon what you want to be able to trust him about? If it is to trust him to make a good relationship with you, I am not seeing it. If it were me, I would not waste my time.
