Should I end this friendship even though I have never did anything inappropriate with him?

My husband use to be nice and sweet to me. But lately he is barely home and when he is he just wants to have sex and sleep. After we got married and I moved away from the states to his home country things began to change, especially after I became pregnant. He works for a Private Security company as a bodyguard in Sydney and spends a lot of time on businesss. His mom comes around alot and she does not like me and will not hesitate to tell me her son is too good for me. I am 6 months pregnant and I feel like I had no one until 3 months ago. I met a guy that lives next door that helped me bring some grocery's in my house. We started talking and he comes over and spends a lot of time with me while I am alone and he is not at work. We have never did anything appropriate. In fact he is a really sweet guy. He did spend a night on my couch one night when my husband was out of town but only because he fell asleep watching a movie, I am afraid of what could happen if my husband finds out because he can be dangerous when angry as he is a very in shape man. However, I do not want end our friendship because for once since I have left the States I do not feel all alone and it is innocent. Should I end this friendship?
