Looking to start focusing on my self but don't want to leave the girls I've been teting

Hey,
I'm looking to only focus on myself and I don't want to just leave. I was thinking about sending to all of them a text letting them know but what to say, this is what I thought about :
" I'm going to leave this app to focus on myself, if you think you should be part of my life, contact me : my phone number "
what do you guys think
