The summarized story; around new years my friends and I are out at the bar and my roommate tells me his cousin is going to stop by. She shows up and I Immediately I notice she is pretty hot, she is 22 and I’m 26, totally opposite of my taste (I like blondes that look like the ”good girl” type , she has black curly hair, cute face with piercings and a tattoo on the back of her neck and wrist, and she smokes), yet there is something that makes me want to get to know her. I talk to her a little and find out we have some things in common and she’s pretty fun to talk to. She eventually gets my number from her friend and starts texting me about her laptop, and I go to her place to fix her laptop for her and we end up talking for hours and hours about nothing, I leave her place as friends but excited cause she seemed to like me. After that night she is like blowing me up thru text, like some days are 50-75 texts totally flirting. I’m just going with it because it nice to have someone take interest in me like that and I’m getting all giddy from the attention, but it did seem a little overboard. We start to talk on the phone and I’m flirting with her, even tho I’m apprehensive because she isn’t my type and I don’t like the fact that she smokes and doesn’t really show any girly manners, she’s kind of crude mannered sometimes. One night she invites me to the bar with her and her roommate, I go with a wingman and we are aren’t drinking. I notice she is talking to a lot of guys, and I’m a little nervous because of the last relationship that I got cheated on happened this same way. She has like a ½ tattoo sleeve on her right arm and we talk about that, she confesses that she is a sucker for guys with tattoos ( I have none, but have always wanted one) and thinks they are really sexy on guys. After a while she comes over and sits on my lap and starts to kiss my cheek and forehead and telling me I’m such a sweet guy and she really likes me, and asks me to come home with her to hang out. I give them a ride cause I’m sober, and before she takes me in her place she says I don’t want to have sex . I stay the night and we don’t have sex and pretty much she tells me I’m the nicest guy she’s ever met and she really really likes me. I’m loving the attention and affection and we start hanging out like every other day and spending the night together and start getting to know each other pretty well. We hang out more, end up having sex after about a week and its awesome. I open up to her and love the attention and affection she gives me. She tells me she is totally falling for me, has never had anyone treat her like I treat her, but is scared because she thinks were totally opposites and she doesn’t want to get hurt. I tell her that the only real problem I have his her smoking and her manners bother me sometimes. She admits her manners are an issue and she wants to get better, but then tells me she is a smoker and doesn’t see any reason to change that right now unless she gets pregnant, and basically makes an ultimatum that if I don’t just deal with the fact that she is a smoker then the relationship is over. I think about it and realize that I used to smoke and quit on my own, my grandparents were together for 55 years and only one smoked and they made it along just fine and were happy together, maybe she will eventually grow up some and being around me more will make her want to quit. So I tell her I’ll deal with it for now, but it still bothers me and I’m making a compromise to keep the relationship going (mistake number one, I know). So we keep going, hanging out, sex, spending time together and everything is great except in the back of my head the whole time I’m thinking this might never work and I’m not going to eventually get serious with her unless she changes. Meanwhile she is noticing that I’m not 100% committing to her and is getting scared and lastnight she told me that i'm the best thing that's ever happened to her and she doesnt want to think about her life without me ..... This is the catch; she is on depression medication, it runs in her family. She cuts when she is depressed and cant handle emotional stress very well, i've seen the scars. She says she only has to when she goes thru a breakup or something really bad, and doesnt even think about it when she is on depression pills. I’m scared shitless to think that now I will be responsible for her doing that to herself if I bail. I seriously don’t know what to do. 1; should I keep giving this a chance cause everything is good except the smoking and her attitude, and hope she grows up ? 2; should I Bail, and risk her really hurting herself and getting out of control. I know everyone is going to say GTFO, and forget about her problems. but i cant stand the thought of her cutting herself because of me, it makes me sick to my stomach from the guilt. any help ?
