How can I prepare myself for the current dating scene?

So a little backstory. I get out the service in 6 months and want to prepare myself for dating and hopefully something serious. The past 4 years I’ve had on and off relationships that ended because of my work and personal reasons, as well as hook ups as friends. I want to get back into the dating scene but I’m worried about meeting someone as well as actually dating for the following reasons

1. I don’t know how to meet girls. Dating apps and websites don’t work well for me as I don’t really match a lot or get a connection.

2. I haven’t been in a serious relationship all my life, most were short and or hook ups.

3. I feel my confidence to talking to girls is a bit low and I don’t know how to keep a conversation/ flirting going. I can be shy sometimes especially if the girl is really cute.

Any advice will help from both girls and guys thank you
