<human>: Can you give me the gist of the text in a nutshell?

We're both friends with the same person and have hung out quite a few times before this weekend. Well we all decided to go out to a bar this weekend and while our friend was off trying to pick up guys, me and her were playing pool and dancing and talking alot. We hit it off really well and have alot of stuff in common, me and her planned a 4 day trip to the beach together in a few weeks and are both really excited. My main concern is the age difference, our friend keeps telling me it will never work because I'm not good enough for her and too young. Because of all of the negative things our friend keeps saying to me I'm getting really stressed, but me and her went to dinner last night and had a great time and have more plans together in the future. I guess I'm just asking for some advice/opinions that's not from someone who we both know. 

A little more details: I am in the army so everyone says she is in it for the money, but she earns way more than me as a legal assistant. We both met through the same friend and have hung out a lot and love doing the same things like rock climbing, swimming, camping and lots more. Idk what else to write but any advice/opinions are welcome and I will answer any questions as well.
<bot>: me and this girl hit it off really well but our friend keeps saying negative stuff to me and I need advice/opinions.
