<human>: Give me a shortened version of the text

I have a good friend I met 2 years ago in the military. She is very kind, caring, and overall a good person but she is EXTREMELY awkward around people, for example: she'd interrupt people to say really irrelevant things not pertaining to the conversation, she'd take really long pauses between thoughts while talking (to the point where others don't know if she's still talking to them or not). When we go to social events, her sense of humor is VERY hit or miss--she'd make an attempt at a really long joke and stumble through it so much to the point where everyone is just so uncomfortable. There is some serious second-hand embarrassment when it comes to her attempting anything social and I feel bad for her but I'm not sure how to even help her.

Here's the thing: she's is her mid 30's and she has asked me multiple times for relationship advice because, to be completely honest, she wants to have a family someday. She has been on several dates and much to her disappointment, she has no idea how or why they go sour. I have seen her interactions with men and it is also terribly awkward and uncomfortable for all parties involved. My question is: how do I put it politely that her approaches to most social situations makes people uncomfortable? I don't believe in offering "criticism" unless I am able to HELP the situation, so this is where I'm at a loss.
<bot>: My socially awkward friend has trouble meeting guys and I don't know how to tell her it's because she makes people uncomfortable.
