DH feeling resentful about bilingualism

[soundevenfruity]

I wonder if anybody can share their experience with me about "selling" bilingualism to their DPs. I am very keen for my son to speak both languages and my DH agrees to it but feels pushed out and isolated in the process. He finds it extremely hard to learn languages and did not progress much. To be fair it is very difficult and not many people would attempt it anyway. I am a SAHM and speak to my son exclisively in my language but we live in a very monocultural area where there are very few foreigners anyway and I do have to speak English to everybody else including my husband. Our son is starting to favour English though he does try to say things in my language and does seem to understand he has to use different words for me and DH. We've just subsribed to cable TV which would allow my son to hear others speaking the language but I understand that he needs more than me to practice it. At the moment weekend groups and a long trip to my country are out of the question. Is there anything I can say or do to change his opinion about bilingualism?

DH tried an intensive 3 month course when between contracts and didn't get any results. I suppose he is one of those people that feel vulnerable during the process of learning (uncertainty of results, making mistakes, not understanding etc). He does not communicate to my family when we were there, I have to interpret. He doesn't understand thier rudimentary English, they did make an effort to talk to him independently of me.

My mother tongue is difficult: nothing in common with English, different letters and pronunciation and words have many forms depending on their meaning or grammar. That's why I think it would be unrealistic to expect DS to learn it later.
