<human>: Can you provide a brief overview of the text?

Two of my college friends have been dating for ~3 years. T, the dude in the relationship, is currently deployed and is planning on proposing to A, the girl, when he gets back. He has asked me to find out what kind of ring A wants. 

The only problem is that A is planning on breaking up with T once he is back from deployment. T hasn't been a stellar partner in the relationship and often is dismissive or just plain mean to A. A moved across the country away from all of her friends and family to live with T and is now alone until T gets back. More recently, A got really sick and T (who has a lot of downtime while deployed) didn't talk to her for almost three days during that time period, despite the fact that he knew she was sick and had the time to talk extensively with me. When I mentioned it to him, he responded with "she's so needy".

So. Um. What the hell do I do? My first plan was to get the ring info from A and give it to T and then encourage them to talk to each other about their issues. I would feel really shitty telling A that T is planning on proposing and A has expressly asked me not to tell T anything that she tells me. Unfortunately, A doesn't want to talk about wedding rings either, "they just make her depressed".

Advice would be greatly appreciated. Show me your wisdom, Reddit.
<bot>: Friend A wants to propose to Friend B and has asked me to find out Friend B's ring preference. Friend B plans on breaking up with Friend A as soon as he's back from being deployed. What do I do?
