I don't see the mixed signals. I think she's sending clear messages that she interested... in messing with your head.
Look, I'm not good at candy-coating, so I'm just going to be blunt:
I think both of you are missing some really important things here. Part of growing up and maturing is learning this thing called impulse control, and learning to see more than 2 minutes into the future. You have to learn that the things you want aren't necessarily the things you need.
So you want your cousin, but it's seriously BAD for your family. Can you not see the consequences for your whole family? Do you want a gf you see maybe twice a year, or do you think you could have a healthier and happier relationship with someone you can actually see regularly, go to the movies with, etc?
How do you see this playing out? Would you hold hands at the family reunion? Is this something you're going to have to hide? Do your parents know about this? If not, do you think they'd be happy or upset?
It's so clear to anyone whose judgement isn't clouded by emotion that this isn't going to work out. I don't know either one of you, but usually when a person gets soooo fixated on pursuing an unrealistic and ill-fated relationship, it's because they're using the person as an emotional crutch, and they're either avoiding something or are in serious denial about something or all of the above. So could you be focusing your feelings on your cousin because you are afraid of having a real relationship? Or are you afraid to meet someone new in your area? Or do you want to experiment with a "safe" person? Why are you putting your emotional energy into this instead of putting it into pursuing a relationship that has a better chance of working out? Are you using this as a distraction to avoid focusing on something less pleasant? Do you think you can't get a real gf?
Think about those things and figure out what's leading you to do something so obviously self-destructive.
And by the way, participating in sexually-charged texting and video chats is a phenomenally bad idea. When you're doing something and there's a good chance you'll regret it later or if there could be negative consequences if anyone found out, then DON'T LEAVE EVIDENCE! Video chats can be recorded and broadcasted online. Text messages can be forwarded in an instant. Once you create an electronic trail, you have no control over it... especially when the other person who has a copy of it could very well hate your guts in the future... and EVERY gf, bf, crush, flirt or friend belongs in that category.
If you keep going down this road, you're just going to waste your time and energy, and end up even more hurt in the end... and possibly hurt your family and make your parents things you're crazy which would make it more difficult for them to trust you.
Think about this and make a better choice... a choice that can lead to more happiness for you and others.
but the thng is I live in LA and she lives in Miami and I knw it wont work out but I just want to get with her and I knw I cant
Then all you can do to protect your feelings is accept that it's not going to happen and move on. Is there a bi/les girl in your school that you like? Does anyone have a crush on you? Is there some other activity you can focus on instead?
no.no les/ I girls are at my school
Depending on where you live, you might be lucky enough to have an lgbt youth group in your area. In any case, focus your attention on your school work. Tons of colleges have active lgbt groups and you'll have access to a larger dating pool. This might be one of those delayed gratification situations.
