Sometimes I think our first relationships are just sort of trials where we are trying to find the right person. Of course you are stressed out, this is all new to you. Before I married, I dated a lot of people who were very bad fits for me. You will take some of the experiences you have had with this partner and use them when you navigate future relationships. If she doesn't make you happy, move on. When I was single, I was certainly searching for an intimate partner to be in my life. Good luck with everything.
