Hey guys/girls I just had a couple questions about managing feelings alongside seduction.

My question has some context around it so let me give you some background. I met a girl after a party back in March. We were drunk and she was gorgeous (solid 9/10, fit, does yoga) and we ended up talking a bit and then hooking up for a few hours by the pool after everyone left. Let's call her Jay. Afterwards she said she had an amazing time and she wanted to hang out again tomorrow. I was like sure and we hooked up again she said just wanted to be friends with benefits. Anyways we hooked up every week or two for a month or two. I had just broken up with my ex in January and wasn't really ready for a relationship so things were good, and she just hit me up to hookup then would leave. We cuddled and slept together and showered together, but it was mostly sexual. I was hanging out with other girls too, but just friends, not hooking up/fooling around with anyone else. One day after sex she said she was jealous of one of the girls I posted a picture with (one of my friends) I told her she had nothing to worry about. Soon after she said she was getting feelings for me but was scared of a relationship (commitment issues, didn't want to be disappointed if/when she had to leave, she's foreign). She said she wanted to end things cuz of her fears. I told her I liked her and didn't want to stop and wanted to get to know her better. Anyways it was mixed signals from then on out for a couple months. I hooked up with another girl a few weeks after she broke it off the sex was good, but not as good. The new girl wanted the same nothing serious and I was cool with that. So for the last month/month and a half I've been trying to plan stuff every week or two with Jay and we've been talking here and there. A few times she said she was down and flaked and so I was pretty much done and gonna stop talking to her and then she would say shit like but I want to see you and she's sorry. I asked her out on a date two weeks ago and she said she didn't want to get hurt, same shit and said we could try being friends. So then we're friends and she comes up to where I live to meet her cousin and we get lunch. We hang out flirt it's chill and then as we're getting to the park she asks me if I ever thought she was awesome. I tell her yea obviously I did and I still do, why does she think I've been hitting her up to meet up. Then she tells me she's likes another guy and she wants to go on a date with him. I tell her that makes me feel pretty upset and she's like no it doesn't. Anyways then we had an awkward conversation of me pretty much being like yea I feel pretty shitty and saying her telling me she wants to date another guy the way she did is quite mean. Then she said friends won't really work anymore we pretty much decide to go out separate ways mostly.

So yea sorry for the wall of text but my basic question is this, how do feelings play into seduction? I feel like I'm attractive, I go to the gym, I'm confident and playful when talking to girls. But then if I start to like a girl it all goes out the window and I turn into a cucked puppy. Especially if I feel like I'm losing my chance to make something happen. Anyways there's a party next weekend and she's gonna be there with the dude (I know him, we're acquaintances hung out a few times) and I was thinking about going and taking a girl that's into me with me. Bad idea? Good idea?
