The thing is, the night she went out isn't the real issue. Dont get me wrong, it was needy as hell and smothering, but the issue is
You 2 moved super fast, doing couple things and being way too invested too quickly. Your needy actions spring from not taking it slow, so any change is going to freak you out. For eg, this happens alot. Guy meets girl and they move too quickly. Talk everyday. See each other all the time. Start planning trips and introducing to family early in. Throwing the word "love" out. Things are "great." One day, chick thinks to herself, "wow, things are moving quickly." She gets scared, realizes she doesnt really know you and you her. "How can he act like this so soon?" Turns her off. Makes her second guess whether the "connection" is real. She decides she's going to pull back. Maybe not text as much. Guy, who is used to speaking everyday, realizes she didnt text good morning today. He gets needy and overtexts, searching for the affection that was there. Girl gets more turned off and says "you didnt give me space today, I was ok, but it was this thing you did today." NO. The WHOLE situation is NEEDY. Not just today. It's just that at some point, she realized you were needy. And it probably was before you texted her last night.

I say this, because you're thinking it was just one mistake. No, you made several mistakes, this was just the one she chose to pull back. When after 2 weeks of sex and 4 months of dating, you're planning the future with a chick, she's going to come out of the trance and realize "he likes me way too much." Last night was just another sign of that. If she texts you tomorrow, youre thinking "ok now things can go back to the everyday talking/lets pick out our kids names" thing. THAT's the problem. The only way this COULD work out for you, is if you realize both of you over invested, and you both need to step back. If youre thinking "wow, I shouldnt be planning trips with a chick so soon" Good. If you're thinking "wow, I wish she came back so we can go on that trip" BAD. YOU have to do as she did and realize things are at an unrealistic/crazy place. YOU have to realize this girl is not your wife. If you continue thinking that things are great/healthy and this fuckup was the only thing to fix, then youve already lost.

She was "scared" from you calling, because she already wanted space. A chick who hasnt realized things are moving too fast, wouldve continued to text you even when she's out because she's still in puppy dog love mode. And she's right, you too should step back. The issue is, you shouldve realized it first. Now, you're in the worse position.

Yeah, as n2thevoid said, it's a matter of seeing the forest for the trees. I didn't realize the whole situation scenario...

She sent me a message yesterday, asking if we could talk today. I suggested a Cafe, she said "Anywhere" very smily, kind of friendly and cute.
Then she asked me how I was going, I said I had better times, but I was ok. She said she also had been better, but she was ok too.
Then she said she was at a party with a friend (who's gay) who decided to take her out of her "sad day". She's not the party type, but we met at this club on the first date. I said he did well, said her to have fun, that I wanted to go there but I would wait until tomorrow, and said "Enjoy the mojitos!" which is her favorite drink. Smile emojis, kisses emojis and that's it..

Let's see how this talk is gonna be. I'm thinking about asking her to come here (home) instead of the Cafe, as long as she said "anywhere". What do you guys think?

PS: Besides it, I'm calm and aware of all the things posted here. Whatever happens in this talk, I think I will be a better man after it. Many thanks again.

Any hints? What do you guys do to put your shit together and don't feel this bad?

Have other options.
