I love this girl but at the same time I don't know what I want. I feel like because of this I do selfish things in regards to the relationship I have with her. For a really long time I had the thought that I haven't been with enough people to know what I want in a partner. I have little experience in dating so I always have the feeling of not wanting to settle down with her. I always had the thought that I wanted to marry her but at the same time I have thoughts of wanting to experience dating other people first. I feel like I meet her at a bad time. I don't know what to do. I feel like I will regret both decisions.
How long have you known her? Are you in a relationship now? If so, then you should probably talk to her that you feel you have little experience. You might talk to your friends/family who could give some advice on how they judge your relationship with her. You could think about taking a break and dating some other people, but if you do that, you must let her be free to do what she wants.
I've known her for basically all my life so it is a big reason why I find this so hard. When I meant "met her at a bad time", I meant more like in a romantic way and not only just platonic. I'm not in a relationship now, I have these thoughts of wanting to experience dating other people but at the same time I am only interested in her.
