<human>: I really have nowhere else to turn Reddit. I've been with my SO for 3 years. We've had a great relationship. We both trust each other completely and we hardly ever fight. Lately I've been having second thoughts about our relationship, merely for the reason that I just want to be single. I've had these feelings before throughout our relationship but they usually pass. Not this time though, I'm constantly debating it and it's not going away. I just want to be alone for a while. I want to focus on me and my life without having to think of someone else. Is this selfish of me? I love my SO I really do. And even thinking about breaking up with her hurts. But what if I ignore these feelings and try to actually appreciate what I have, will it just be delaying something that's unavoidable and one day realize she's not the one for me? Its tearing me up inside. Can somebody please give me any kind of advice.

Can you summarize the given text in a few sentences?
<bot>: Good relationship. I DO LOVE HER. Constant thoughts of ending it though just to be single. Should I appreciate what I have or let her go?
