I'm wondering if what i did is a normal response

i had a friend when drinking we would sometimes kiss,sometimes show her breasts, be nude in front of me. one Mon i was sitting at home,and she im'd me that she was hanging out with 2 guys a dog and ALOT of vodka. i said i was gonna just hang at home figuring she was trying to make me come up there because i was jealous (i asked her out 4 times). she then im'd me that she wanted to kiss someone but had no one to kiss. i decided (against better judgement to go up to her appartment. while on the way she was im'ing me are you cummin', and kiss kiss when u get here. i was im'ing back where i was i.e. how close i was getting. after i got to her place i could see she was somewhat inebrieated sry about spelling. she was still im'ing me while i was in the room (with the other 2 guys and the dog) because i receive im's on my phone. she was im'ing me stuff like suck my boobiers (which i took to mean her breasts) when can i kiss you, can i kiss you with the kissy ears on errr kitty ears. my responses were you can kiss me whenever, gimme the chance lol (on the breast one) and yes you can kiss me with the kitty ears on. she at one point in the evening asked me what i was doing the next day. i responded by saying i was going to court. she said i should stay over and something to the effect of whatever happens happens (which i took as sexual) she also was playing spin the bottle but wasnt kissing anyone (i noticed it didnt land on me) she then asked me to spin (it didnt land on her) so the game promptly stopped. she then sat in one guys lap as he cupped her breast, and kissed him just a peck. at one point as i was also getting drunk i mouthed to her i want you. she didnt hear me so i whispered it to her. after the game got over she sent the other two home. promptly kissed me twice got into her pj's , but while doing so told me its ok if you look i said no thats ok she then said it again but louder so i figured what the heck and did. im sry but before she got undressed she reached behind her and grabbed my crotch thru my pants (at least thats what i remember) after getting dressed she lifted her shirt. i saw then that she was braless. she told me that because she had been eating healthy that her tummy had gotten in better shape. and asked me to feel it then said her breasts were now less saggy (my recollection is that then she grabbed my hand and brought it to her breast) she doesnt remember that. we talked for a quick sec i then exposed myself. she reached her hand out and touched me for a second. i then put myself back into my pants. she said she needed to go to bed so i got up and headed to the door to leave. we kissed again. i left. the next day she called and asked why i had exposed myself. i said i got drunk and i wasnt sure why. the next day she freaked on me said i had no right to expose myself and that the friendship was over. now im left wondering was exposing myself totally wrong or because of the other circumstances was a normal response.
