Need some advice please “What to do”

So let me start to introduce myself. First off all I live in Europe so my English is not the best sorry for that but I do my best to write this and explain my problem. I dont want to use my rl name you bro’s can call me out by my nickname: haatjee.
I decided to doing nofap aswell because in my rl sex or head etc I experienced a erection problem I think the reason for it is porn since I have every morning erection and when I fap my erection is normal. But When I have real sex it is not rlly hard enough sometimes not even getting there.. In real sex in it possible but the girl really needs to turn me on I mean REALLY REALLY turn me on. I was maybe fapping 4 times a week. But this is not the problem where I need advice for.

So there is an girl in rl I know for like 3 years I guess. I never really liked here from the start but I thought she was still hot but without feelings and I know she felt the same way as me. Let me explain me I am not a needy guy etc I have experience with girls I know how to talk. When I met here I created comfort with here to get more
open each other. So she told me she was still a virgin and even never kissed before She is 19 I am 22 now. And I told here I was not a virgin anymore etc. So we met up And kissed here.. a few dates later we started touching each other she gave me head etc but allways we still never got feeling for each other. And in the 3 years we also had moments when we dont talked for weeks or months either I contact here but I never did that to much since I dont want to give here a needy vibe. So when she lets says contacted me lets say after 2 months I was sure we can meet. And a few months ago Idk why but suddenly I started to like here and we dont even snap/text each other everyday. It just came and last week She asked me to hang out I invited here out to my house she came it was the first week also in my
journey after 2 days already I cummed
in here mouth already I hope thats legit tho. But I even started liking here more and more when I was with here I started to imagine how I could take care of here and love here even when she was next to me lol can you imagine that ?

Since I like here now I want to talk to here everyday but she almost never text me first so this annoyed me now. I decided a few days later to tell about my feelings, in the hope she felt the same way. So I snapped here and asked If she is fine If i pick here up from work she answered that she would love that. So I picked here up started casually how the days passed than drove to parking place and told her about my feelings. Guess what she didn’t feel the same way. She said I dont think we will end up together it is impossible she said so in other words she said you are not the one I will be ending with. (but she is open for friends with benefits) wtf means this this really confused me... when I heard this this really really crushed my heart but I didnt showed it to here I acted I dont care but deep inside I was burning. And than my I brought here home and drove with a shitty feeling to home...

My bro’s I really like here what should I do I dont understand she is open for friends with benefits but not relation I dont understand man what Should I do fully ghost or what. Sorry for this long message thank you guys...

Peace
