I need advice

I have recently been in contact with a guy living in Tunis. We have been webbing over 2 months and everyday he has't stopped texting. A few weeks bk he stated that he is down and depressed due to not having a job any longer. He said he had bills to pay because he is alone with his Mother. He didn't ask directly, due to seeing him so disheartened I sent some help, including to help top up his wifi which recently expired. For a while now he has spoken of really wanting a life with me including having children, he mentioned that by this time next yr we have to be together and act, he is wishing to come to the Uk for study and eventually work here. Discussions are often intense
However, a few days bk he mentioned he would be embarking on a journey to the South of Tunisia with his friend who is a lorry driver and he said for 7 to 8 days he will really miss not contacting me via web in the evenings, but he would not let a day pass without texting me. It's now 2 long days no contact, he hasnt been on line, I myself have travelled to Tunisia lmany times, including the South and I know for sure that if u really want to contact u can find a way. I also booked tickets to go to Tunis to meet him next week but after this total silence I have so much worry and second thoughts. I just need some opinions regarding this matter, I feel so disappointed and all this silence is followed by question marks. Please help
