As you realize, this is quite a dilemma. If you voice your feelings to the friend, you risk losing your girlfriend, her cousin. If you risk telling the friend how you feel, she could reject you anyway. And whether you choose your current girlfriend, or her cousin, one or even both might conclude you are a person who betrays and isn't very nice. Very difficult!
It sounds like you spend more time with the cousin (daily), than you do with your girlfriend. Perhaps just goofing around in the games you play makes it seem like you're closer emotionally than you are in truth. It's easy for a girl to flirt, chat, etc. when sharing time in games. It doesn't mean she's romantically interested. In fact, perhaps she feels so comfortable with you in the games because she knows you date her cousin. When a girl knows a guy is off-limits, it's so easy to be best buddies with him.
Now, to your girlfriend you've dated for 2 years... She expects and deserves faithfulness, including emotional faithfulness. Undoubtedly, she'd think you're a jerk if you hit on her cousin!
Perhaps you need to take a break from both of them and see how it feels, who you miss most. Maybe a couple weeks by yourself will give you clarity.
Perhaps it might be best to draw yourself a personal boundary here. Either close the door to the feelings, or stop talking to the cousin altogether. it's hard to set a boundary, but it can be done without ever telling either girl what you feel (felt).
However, IF you choose the cousin, the fairest thing would be to break it off with the girlfriend FIRST. Then, wait some weeks to months, and then check out your feelings with the cousin. BUT if these 2 girls are close, it could blow up in your face regardless. Just think about how you'd feel if a girl dumped you for your cousin/close friend! It'd be awkward to see them; one or all would feel hurt and angry.
Whatever you do, don't cheat. Try not to hurt your girlfriend. Be honest, but respect her enough to break it off before picking her cousin. And make sure this isn't just a false sense of closeness with the cousin, before you ruin things with your girlfriend.
Well you could let it go or you could tell your friend if you think it would change the situation.
Tell them
You should tell her, they should be ok with it because they are not in love with their cousin and plus if she is really your best friend it will be cool with her.
Why is this a problem for you? Is your cousin a bad person? Is your friend a bad person? If the problem isn't a safety issue then you should wish your cousin and best friend a long and happy relationship. You may want to ask yourself if you're just jealous of the relationship they share.
if they are your best friend they should understand
You should go up to your best friend and talk to her and then is they approve go talk to their cousin I like my cousins best friend and ive talked to him.
just tell him and get over it you should feel happy for her she is your best friend
you should also join and enjoy
you should try asking your boyfriend to talk to him
no
Talk to her about it.
I think you should ditch your best friend and replace her with another person who won't betray your trust by dating your boyfriend. That's what you should do.
Just say it. It is your cousin, not your lover. It is his best friend, not his pole smoker...
well if you like your best friend then you should go out with him|her... but if you don't your best friend then you should tell him|her, that you are going out with someone already.
