Hi all, I finally approached a few weeks ago after about 2/3years of trying but got a couple of problems.

About 3 weeks ago i finally did my first approach (2 set) i could not get my words out so i figured i probably fucked that one up moved away from them a couple of feet and went on my mobile then moments later they reapproached me had a good convo for a minute or so, i was speaking to her friend as the one i was hitting on was really shy so ended up going through her friend and she said i have a boyfriend (i was like wtf i was hitting on your friend not you) which i said "oh" then she mentioned she's also got a boyfriend which i replied "that's ok i'm not the jealous type" just for laughs. but the weekend just went they spotted me again and smiled and told me to come over which i did but as i did they moved, it seemed like they wanted to play a cat and mouse game which i refused to do then decided to browse on my mobile for about 10 or so minutes i noticed they kept hanging around within 10 feet of me so i then decided to reapproach them and simply said "hi" the shy girl had looked like a rabbit in the headlight so that in turn freaked me out and decided to abort. then on sunday they spotted me again and still they kept followinig me and hanging around me this time within 4 feet every where i turned they was next to me or following me -_- admittedly i'm 28 and she was 17 and the other was just under 17 and yes it is legal in the UK , how do i stop this stalker? it's starting to piss me off

my second problem is i can't seem to get back into approach mode again -_-

tl:dr how to stop a stalker & and how to get back into approach mode again i've only approached once :/ seem to of fell back into my old state

thanks in advance guys
