It sounds like there were rather a lot of ‘little things’ in a short space of time; it’s ok to feel like you didn’t deal with them well. Some things you’ll deal with better on another day. While you hate flipping people off, it’s good that it made the other driver think a bit and back off. Impatience can be a killer!
I really like how you acknowledge you’re worth more than what this man is willing/able to offer, even if you might wish things could be different. I‘ve often found it hard to step back and get a little perspective when I’ve had strong crushes before.
Hope tomorrow is better for you!
