If you have had a LTR with someone who was reliant on you, then yes. It will affect you. Their path in life is not reliant on you, putting your life on hold for mr/miss perfect is not a good look.
But, if your new chap has friends, a job, and a social life and seeks a relationship with you to enhance it, that's different.
Agree to stop discussing it with him at once and just date and enjoy being someone's girlfriend. If he is needy and if you go out with your friends and he is at a loss, that's a problem IMO.
But not your problem iyswim. Just carry on, taking things at your pace, you'll get closer or you won't.
