did i do something wrong ? i want a serious relationship with her but im confused

hello guys im new here and i have a little problem , im sorry for the long post
i met this girl that i like we started seeing eachother, texting alot everything is fine
i went to her place twice nothing happened i was massaging her back from under her shirt while she was on top of me while kissing her neck , when things got a little more physical than just touching she stopped me , i tried putting my hands in her panties but she took my hand away and said no , second time when i slept at her place she turned her back on me and said good night and i grabbed her from behind trying to escalate things a little but she didnt respond at all , i mean she would let me touch her until some point and thats it she wouldnt respond with a little touching herself when i tried to kiss her she didnt respond to the kiss she held her lips tense

thing is she also hangs out with another guy from our group of friends Alex i asked her about him she said that they are just friends and i shouldnt be jealous they go eat toghether , shop toghether

whenever we hang out she notices guys checking her out alot , i dont see it to be honest , for example we were at a car wash and the guy with the car behind us told her that her front tier need more air which was true and she was like " did you see how he looked at me ? if we were staying any longer he would have offered to solve it himself " stuff like this

i was at her place once and she was texting with alex and i told her whats up with that and she told me that im too jealous like wtf? and she started ignoring his texts but he started calling her , she rejected 2 of his calls at the 3rd i told her to talk to him because he is starting to annoy me and she went to the bathroom to talk to him .

All my friend sayd that i should have just left when that happened and that she is nothing more than an attention ***** and that she is just teasing me and Alex . One of my friends even told me "You can try to be with her but you wont have sex with her she will let you touch her a little she will tease you but thats it nothing more " and that is exactly what happened 2 times in a row . I asked him how did he knew and he didnt wanna say im guessing he tried aswell Its funny cuz she even sent me a meme once that sayd "Me in a relationship : I need attention"

and the worst part is that i found out that she is in a long distance relationship . They have been toghether for 5 years now and her boyfriend has been out of town for almost 1 year and he might stay there for another year in worst case scenario . She even told him through text that she loves him while she was with me . But she said that she might break up with him because they dont get along anymore
I asked a friend for advice because it felt kinda weird to pursue a girl thats in a relationship even if she want to break up with her boyfriend and she got upset told me that she didnt wanna talk to me anymore but ofc she started initiating again sending me pictures and stuff
should i continue to hang out with her or should i just give up ? i want a serious relationship with her not just sex

 

Its too bad we feel so good when we are toghether
So there is no chance that she migh actualy be a good person ?
It hurts so much when i see her hang out with alex , if they end up toghether its gonna suck for me because i see them almost daily

 

How can she let someone that has no feelings for massage her , sleep in her bed she didnt seem this kind of person at all

 

I doubt this kind of stuff would happen i went 28 days hardmode and nothing special happened except higher energy levels

 

is she really that bad ? )
i did see some bad things about her but not that horrid

 

i was thinking that maybe if i treat her good unlike her boyfriend and wont be in a distant relationship with her things might be good
a friend told me that she might be waiting on the break up with her boyfriend until she decides between me and alex

 

i was at her place yesterday she constantly laughs when she sees me she says she doesnt know why, she wants to annoy me all the time but again she doesnt know why she says that she just wants to do it and the fact that she cant do it makes her wanna do it even more , we stayed in bed in eachothers arms she was resting her face on my palm it was like we were getting along good but today i messaged her if she would like to hang out and nothing she left me on seen and thats it no respond

 

she didnt lie about having a boyfriend she never sayd that she was single and even after i found out about boyfriend we kept hanging out at her place things didnt change because i found out about boyfriend actualy thats when she opened up even more to me because she started complaining about him how he treats her like crap since he left town and stuff like that
