Venus Mars and Mercury in Sag here, with sun in Cap and moon in Pisces. I would say yes I fall in love often and I move on also fast, but this also depends on who it is I am falling for. I am actually often in long term relationships, thanks to having Cap and Pisces. But I do believe that no one can 100% be the perfect partner: something gotta give so to speak. My current partner I have been with for 6 years, I love him to death and he takes good care of me. But our stable relationship lack a certain cerebral and adventurous quality that the Sag side in me crave. Therefore I still get infatuated pretty often, seeing others as potential “adventures” whether sexually, intellectually or emotionally. I will never act on it though since I fully understand these feelings are purely for the thrill of it all and different from what I have with my partner. This has been a difficult thing to navigate regardless since I have these sag placements in the 10th house, I often get noticed and pursued by others especially in work relationships. I could totally see a less responsible commitment-free version of me running wild and getting in tricky romantic situations.
