i need help

so basically me and this girl met online almost a year ago and we were good friends for a while but one day she confessed to me. the relationship was great for like 3 moths but then she started not answering the phone as much, and getting busy with other things and i started feeling like i was the only one putting any effort into the relationship. i talked to her about it and she broke down saying she was going through a lot and she promised to put in effort. and she did... for about 5 days until it just went back. i just missed the way we used to laugh and talk when we were friends, i missed her. so one day i told her how i was feeling and we agreed that we both have a lot going on in our lives and we would be better going back to being friends. and that would be great if my feelings for her went away.. but they didn't so I've spent the last 3 months pining over her. i honestly dot know what to do. today she told me she felt the same way and still had feelings for me. i was excited but things just don't feel the way they used to. our conversations don't flow like they used to and we aren't laughing like we used to. idk what to do, she's my first real love and i cant get over her but i don't know if i want to be with her like that. help.
