<human>: Can you condense the text into three sentences or less?

Hey! So my best friend [16/M] has had a relationship with a [16/F] for about 2 years, and they really like and love each other. Recently, she wanted to take a break from the relationship to figure out some stuff. After 2 days, she broke up with him. He was crying and all sad and I was the only one he trusts enough to help him out.  

Of course, I  helped him out and everything and he now feels better(a week later) and "over it". Today, she approached him and told him that she misses them being together and misses him by her side. She tells him she left him because she felt guilty because she has depression and thought he would not like a depressed GF. He also feels guilty because he was once seduced by another girl while he and his gf were on a little break from the relationship, but he held himself from kissing her or from getting intimate. He told her that to tell her that both of them feel guilty. He told me that they are now just being friends and one day, after they fix themselves, they want to get back together(at least he wants to, she looks like she wants to). He asked me for advice so I came here. Help me help him please.
<bot>: My friend's GF wants them to be friends until they get back together one day, this happened after a week of their breakup. What should my advice be?
