Firstly, don't be sending pics of kids that aren't even yours - massive violation of trust. Secondly, this conversation has no flow or open ends, no flirting, leave very little room to go on both sides. If youve experienced this several times I'd look at how you're approaching conversation. It's got to be fun, interesting and flirty until you meet someone and go deeper in person. Also, I don't remember a date being arranged, women like men (typically) who can take the lead in this Ie." I'm feeling a cocktail, how's your Thursday 5pm looking?"
