How to make a move on a in closet bi guy?

k so this is going to sound a little weird but the thing is he acts gayer than me. like i recently have accepted being gay told him i am and most imporrtant have told him that im actually into him. he told me hes straight didnt tll me that hes not interested but the straight answer should be enough. He leaves alot of hints that hes flirting with me. All my friends tell me that hes flirting with me clearly by doing things like feeling me up, getting turned on while lying on me, stealing my bed and staying on it while im in it with him but hes only done that a few times, also he does alot of very intence sexual touches on me such as rubbing my leg a little or putting his manly hand all over my body, also he jokes like just recently he said that on prom night hes going to wake me up in my tent wen i sleeping and how were going to have fun together. Like he knows that i like him and he can prob see it too, or how wen i asked him what he was staring at and he was like just u cutie. Although he does all this stuff that makes him seem interested in me its all so confusing because hes always re-enforcing the idea to me the he is 100 percent straight. Like wen we go shopping together and yes he likes to shop for clothes. He will look at a girl and be like damn shes hot or wen we are driving will make the motion that hes gonna honk the car horn at some girl. he also feels the need to talk about girls sometimes. as in i would do things to her or how hes gonna bang some chick on prom. But hes also done things like at one party he got rly drunk and high and told one of my new gay friends that he's bi and tried to makeout with him. im thinking that flirting back will help, but i dont no how to. if possible like sexual touches would help alot cause hes resorting to that alot lately. oh yea also hes started doing this "joke" where he does a stripper dance and starts taking off his pant, hwoever, although there are other ppl in the room he is only looking at me. p[lus hes gotten on top of me before and clearly gottne turned on but still always talks about girls and is very sensitive to gay things that he does and feels the need to tell me how they arent gay. please help im clueless on how to make moves
