Suddenly lost the fire??

So I’ve been dating this girl for a month now and things have been going pretty great, except, suddenly I felt like I lost the fire?

A little background, I met this girl through a mutual friend when we went to hang out in the mall and we were off to a great start. We shared similar hobbies and interests such as liking the same movies, sports (we both liked tennis) and even games etc and even have the same humour and values as well.

So then I asked her out for a few dates just to try and get to know her properly and after those dates, I eventually started liking her and asked her out when we went to the park on a Saturday. She also said she liked me too and so we held hands. I also told her that I kinda just wanted to take things slow and see where it will go since I thought maybe these feelings could grow.

That day, I stayed overnight at her place for dinner and in the heat of the moment we kissed and made out (but there was no sex) and things were heated between us. Went home on the Sunday, and went back to work on Monday and was missing her like crazy for the whole week. I asked if she wanted to meet up again the next weekend and she agreed. I came over to her place and decided to go out for lunch at a cafe and we had a long talk about our past and shared some stories together. Went back to her place and made out again and did some foreplay.

Come this week after coming back to work, for some reason, I don’t feel that strong passion anymore like the previous week and I’m honestly confused as to why I just lost it.

The girl I’m dating is cute, caring and very sweet and ticks all the boxes for me but for some reason, I don’t feel like I’m missing her or anything anymore and I feel weird.

For me, I haven’t had the most extensive dating experience so I’m pretty new to this and I’m confused if this is normal or not.

Thanks for listening guys

TL:DR I felt very passionate about this girl I’m dating but then feel like I lost it
