Is it fine to chat with another man if I am separate from my husband?

Hi,

I was living in the same house with my husband in a separate room. Last year I sent him a legal notice for divorce and he did not reply.

Recently I met someone online who looks like he could be my future partner. My question is:

1. Is it considered illegal to chat with someone online?

2. My daughter (16 years now) is against me for chatting with his person, does she decide on her custody?

3. My hubby is claiming the jewelry and gifts that he gave to me and my family.
