You guys dated as kids... it was a childhood crush. It was over 11 yrs ago & your still young & you think because now you see him as a man & married that his wife took your place & you could have possibly been with him now & with a child from him possibly. But you had your chance & runined it. You let things & people get in your way. Guess what sweety! There is alot more in your way now & I think to get it off you chest first you should tell the cousin the man your now dating the whole story & hopefully he doesn't think your an inmature woman with a childhood crush & dumps you on the stop for even putting your current new, good relationship to crap over a CRUSH.... Then you should at one point tell this guy your ex now married man in a friendly setting like at a coffee shop how you felt as a kid for him & how you still find him attractive. Wait for his response but please don't flirt or touch or do anything to entice the situation remember he is a man & what you want is to know if there was anything mutual between you and him in the PAST & further more if he STILL feels that way. Whatever he tells you just listen to every word very carefully & embrace the whole moment beacuse its a moment you've wanted for such a long time. But he is now married & you should respect that. The world turn & you wouldn't want someone taking you husband. Period. You have the cousin a close relative of his & you should work on that relationship & even thought you cant have the now married man you can have the cousin & i'm sure there are similarities between them. See where that takes you. The past is past work on the current. Because you wouldn't want anymore what if's.. Even if it doesn't last atleast you put work into this relationship & didn't run away because of this mother or whatever lol. Atleast now you've told your feelings to both men and are completely honest with yourself & them & move on... Good Luck!
