Losing feelings?

So I’m dating this girl and I have been for almost a year. I used to really like her, maybe even loved her. I would think about her all the time and you know the cliche butterflies and everything. Nothing in our relationship has really changed since then but for some reason, I just don’t feel the same as I did before, even though I think shes great and everything and theres no reason for my view on her to have really changed. I went from being in love to now just feeling like strangers.

I think it could be personal issues maybe, because I’ve heard people say that you need to love yourself before you can love others, and loving myself is definitely something I’ve been dealing with so, maybe thats it? I’m also a girl who only came out as bi a year ago and so this is still kind of new so sometimes this makes me wonder if I’m lying to myself about who I am. The worst part of this is, I still love her whether or not in a romantic way and I don’t want to break her heart so how could I ever tell her this?
