Should I reconcile and continue with my Sagittarius or move on and start something new?
I got a clear no for this one but feel like it'll be hard for you to cut ties immediately. Towards the beginning of next year, you'll be in a better place to "dissolve" this connection. The person your speaking of has a lot of sexual energy and it's apparent that there is a strong physical attraction but the issue is that there appears to be some manipulation and game playing as well. Overall, it would be in your best interest to move on. This person isn't good for you emotionally.
Someone who is more honest and consistent will be better suited but you'll have to work on your perceptions of what you deem "exciting" and your idea of love to accept this type of partner. You've got good energy, don't let the bullcrap weigh you down.
Trust your gut!
