I had a dream about how happy I would be in a relationship with a girl who I'm going to meet in a few months. I want to break up with my current gf based on that dream. She won't pick up the phone

This new girl is sweet, just out of college, 3 years younger than me, very family oriented, wants to have 2+ kids and I always talk to her while going to work

She's away on a sales pitch for a few months, we keep in touch regularly and when she comes back I'm going to ask her out officially.

My current gf is doing her master's and she has less and less time to spend with me. I hung on to her thinking there would be some resolution but so far there hasn't been any

I'm tilting towards breaking up with her via a call and telling her not to text and call me anymore (and hope that works).

I wasn't sure this was the right thing to do but the dream I had convinced me 100% it is the right thing

What do you think !besties
