Are these feelings normal? (Women in relationships)

So I was in an abusive relationship for 6 years, mentally, physically, and drugs were involved. I was soo used to be treated like absolutely nothing and eventually I had the will power to leave him, I was only single 6 months till I met the guy I'm with now, we've been together for a little over a year and he's my best friend. The one I look forward to seeing everyday. The one who's showed me what a relationship is supposed to be like. I've done such great things since I left my ex and my bf now supports me all the way! I couldnt imagine having a better SO! He's the one for me!! but sometimes I feel like I wish I would have stayed single longer to have that great experience, ya know? Idk if these feelings are normal? I love my SO more than I have ever loved a man, I don't want to leave him but is it normal to wish I could go out and do single things? I would never cheat but they're just thoughts in my head occasionally, is that okay? I just feel like I never gave my self that chance to really be single. I just want to know if ither women love their SO and it's still normal to feel that way sometimes
