Brief Answer:
Behavioural therapy can help

Detailed Answer:
Hello,
Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
Its unfortunate that the effect of your marital problems has affected your daughter. The best possible solution is that you start staying together with your husband and go ahead with marital therapy to reduce the marital conflicts. That would be the best for your daughter. I have seen many bad marriages recover after marital therapy and you being a social scientist, you can well well understand the importance of seeking a help of a marital therapist in such situations.
If that is not possible then then behavioural therapy can help your daughter overcome her problem. Initially you can encourage her to communicate and play with a smaller group having 2-3 children. May be you can arrange some small parties like "pop corn party" or a "maggie party" and invite other children home. Each time she interacts well with other children she should receive a star and ones she has 5 of them, she can exchange those stars for a reward. Reward can be anything that she likes like may be a dinner outside or a barbie doll or a visit to a play zone etc. Overtime she will realize that her appropriate behaviors are being rewarded and then the expected behaviours will improve and increase. But this will take time and requires lot of patience.
She is too young to get involved in various other cognitive therapies and behavioural therapies should be best for her.

Hope I am able to answer your concerns.
