im starting a diet myself and im telling you KEEP MOTIVATED, if you really want good advice 1 in ur the right place 2 u have already got what i was going to say, about lean meats, veggies etc, water.. w.e all great info
but for the relationship advice, right now i have 2 girls on the go... frankly, if u make this guy the object of ur attention and u dont have any other guy lying around.. in the begining stages
mention other men (a few 1-2 ) as competition playfully... i had this done to me the other day, and its a great OPENING for the guy to brag about himself, and for u to playfully say 'maybe.' or your right ' you are cuter than him but..... ' this adds some doubt, and some easy flirting.
second of all, if you think he likes him.. maybe its just me but im TELLING YOU. add some assertiveness or aggression i have gotten sick and tired of chasing, if u chase back at LEAST alittle, i swear to u.. he will like it, what guy doesnt like feeling cute/wanted once in a while? i mean hell lets appeal to mens laziness... girls coming after us? WOW SWEET!
also if you can spend time alone, and get to know him, that will help, and your attention to your body.. he will lie, but it will arouse him.. my ex would go to the gym with me and some times i would watch her sweat, stretch, lift weights, and try her hardest, she was playful sometimes and talked more than she worked, but she made me feel like an expert at everything, and she also looked attractive because she cared about her body, and did something about it, also take a shot at his manhood if he doesnt hit the weights that often
also: playful always wins with flirting,
wow sorry longwinded, but good luck!
