You just have to build it up slowly again. The more you are around people, the easier it will be. Start off by making friends with other guys. Go out and hang with those guys. I'm sure one of them has a girlfriend. Have casual convos with them. This is how you build up courage to talk to girls. I'm sure she'll have a friend or two that she'll hook you up with and do the same thing with the new girl. It's all about building up confidence. Just don't overthink it and you'll be fine. Remember, it's a process. It doesn't happen overnight.
