Expats groups and other advices for an English coming to Paraguay

Hi there all, hope you all doing ok!

I'm not an expat, I'm a Asuncena who spent 6 months in beautiful Brighton England where I met someone in who's now willing to come to Paraguay and live for a couple of months, potentially together.
As a paraguayan myself I'm aware of the huge differences in lifestyles, quality of life, the lack of interesting things to do comparing to England, and  I'm really concerned about making the most of his experience here and I'm trying to do some research to make things as easier as possible by the time he arrives.
I would like to know if there's any kind of expats group in Facebook which I supposed is the easiest social net, where he could get in touch whit other foreigners living here who could help him learning spanish, gatherings, job opportunities, socializing and tips for getting by in here. Of course I can give him my advices but it would be from my perspective that might be much more different from people of other countries. Appart from that if there's anything you would like to add, tips, advices or suggestions they would be very much appreciated.

I'm very aware of the bad, the worst and the ugly of living here and is making me a bit nervous about it but I think if ther's some kind of network support this could turn into and interesting experience for him.

As a side note we are in a relationship, he's my boyfriend eventhough we've been together fisically for around 5 months there in England, 5 amazing months were I grew to develope very strong feelings for him and I think he has too, there must be a reasong for him wanting to come to this very "special" country. If anyone in here has experience in this type of relationships I would like to know what are your thoughts, experiences or suggestions.

Looking forward to hear from you and thanks in advance!
