How to handle anxiety? Feeling lost

Hello guys, how you all doing?

So, I'm 25 years old (M) have dated few girls before and just one of them (dated for three years) I count as a more serious relationship. This relationship made me feel great, was one of the great feelings that I had felt (2015-2018)

In April i started seeing someone that I had a crush since mid 2018, we started to talk and etc, so at the end of the quarantine I asked her out (yeah, the quarantine is over at my city)

She couldn't the first time but then three days later she asked me out and picked me up at my place. The next four times we hanged out I asked her out, she always said yes (two times she couldn't because of the job but she always reschedule and suggest a day that she could. And the last time we had sex for the first time

I'm feeling something so good with her that I haven't felt since my last relationship, even stronger.

But sometimes I feel an impression that I'm to needy. We almost don't text because she don't like too much neither do I, so we keep interacting when we send each other a picture on Instagram or when I text her to go to a date and a day after the date, then the conversation stops

Today I called her out to go to a little trip to a house of friend of mine spend thr weekend there but she can't because the birthday of her bestfriend

My point is, I'm feeling something that I never felt before, I really enjoy spending time with her, she always seen to have a great time with me (was her suggestion to go to a motel last time to have sex)

This feeling that I have now is getting me anxious because I don't want to screw things over being to needy and I really enjoy her company

People will say, focus on yourself etc, I'm really focused at my company, my family and friends, always have been focused actually,

What can i do? Some friend of mine told me something like that: "Wait her to call you to do something, it was always you that called her"

Other one said: " just be yourself, if you want to call her again, just call it, she always said yes and etc"( just this time that she has her bestfriend birthday that she can't but she didn't suggest other thing to do)

I'm feeling kinda lost to tell the truth, feeling anxious because I'm hanging with someone to have the same objectives that I have for life, enjoy the same type of life, hobbies, food etc, and all of this make me have the impression to be to needy (even if I'm not, am I? Hahah)

Sorry for the long text

If you got this far, I hope you have a wonderful day!
