<human>: Can you provide a brief rundown of the text in within 3 sentences?

On the weekend I gave my number to two guys I wasn't really interested in because we'd been chatting for quite a while and I felt it would've been awkward not to. Both of them messaged me, but I really have no desire to go on a date or engage in small talk via text. So far both have just asked me how my week has been and we've engaged in small talk, so it would seem kind of preemptive to send a "Sorry, not interested" text when they haven't actually asked me out. Should I just stop texting? Seems kind of harsh. Also, one friended me on facebook and I feel a little nervous about him knowing so much about me.
<bot>: I don't want to have text convos with people I'm not interested in (I'm bad enough at replying to my friends' texts) - what's a polite way to indicate lack of interest?
