<human>: Could you distill the essence of the text into 1-3 sentences?

Long story short. One of my best friend's aunt owns a beach house in our area. My friend thought it would be a great idea for her and her bf, me and my bf, and her friend and her bf (these last two I don't know) to go there and spend Valentines day weekend together. 

I wasn't very comfortable with the idea, for 3 main reasons.

1. It's Valentine's day weekend. Valentines day is for couples, not friends. 

2. The other two people I don't know. Not worried that they're dangerous or anything, but it could potentially be awkward.

3. My bf is unemployed. Money is very tight for him, and since it is her aunt's house and her aunt is also in an uncomfortable financial situation (who isn't), she needs us to pay. I wouldn't mind, but my bf would have trouble. I could pay for him, but he won't allow it.

I've expressed all 3 concerns to her and she brushes them off and goes on to say how much fun we'll all have. I'm really at a loss for how to tell her we don't want to go. She's one of the types to take that fact personally, and I don't want to hurt her feelings.

She has even gotten desperate to get me to go, and sent me a text message last night offering to pay for me and my bf, and do extra work for her aunt to make up the difference. [This] is the conversation this morning following that text message. 

I'm really at a loss for words here. How do I tell her that my bf and I don't really feel comfortable going, without hurting her feelings? Again, she is super emotional about this type of thing and WILL take it personally.
<bot>: Friend is offering to pay for the bf and I to spend Valentines day weekend with her and 2 people we don't know. I simply do not feel comfortable and she will take it personally if I tell her that.
