When sex enters a relationship everything changes and your thinking is going to be challenged for 6 months to a year. Don't trust your thoughts during this period. Don't make any big decisions together. If you get to two red flags, again, BOLT.
Let's build better relationships as we pick up the pieces and move forward.
You've got to keep going. Your partner is out there. You've got to stay true to your path, true to your goals and boundaries, and give each person the flexibility to show up in your life and be a YES.
If the chemistry is on and flowing both ways, you will both be asking "What's next." If it's not mutual, move on. You will not be able to build a fire without initial sparks. (But don't overlook the slow-burn. If you're "sort of" interested, perhaps a second date is in order.)
