If you really like him stick with him. Dont let your "friends" ruin your love.

What do they say about him? Sometimes, people do see things we don't see in a new potential partner, because they aren't lust blind, and then months later we see exactly what they were saying and regret not listening.
If they have genuine concerns, find out why and weigh everything up. If they're just being bitchy and just saying stupid things, they're just idiots and not great friends and I bet will be the type who her girlfriends never hear from when she's in a relationship.
