Advice for divorce,child support when wife earns twice than me?

[aliwaqas]

Hi
can someone help me please.
I got married in July,08,to a GP.She told me she earns 100,000� plus her private work.She already had 3 properties in her name,bought before our marriage.I was living in Scotland in a hospital as a junior doctor at the time of marriage,earning about �40,000,she works in London.In Feb,09, I was able to get my transfer to London,as she point blank refused to move or visit me.
At the time of marriage she was pregnant and after 5 months we had out lovely baby.
After 2 months of living together in her london home,she kicked me out,saying she has proof of my infidelity,which she never showed me.Also,I received a police caution for holding her wrist,long story,but I was investigated by GMC and once they found out the true story I was cleared of any wrong doing,but still have a police record and caution.
Now after 4 months of failed efforts and I have received an email from her solicitor saying she wants divorce on grounds of infidelity and aggressive behaviour.
I want to know what my rights are,for contact with my child as she is only allowing 1 hour,every 2 weeks,only if is feeling better.She is 6 months pregnant again.
Also how much child support i should pay?
Also am I entitled for any compensation?as I paid for plane tickets for weekly travel form scotland,her entertainment,grocery shopping when i was in london and when she was in scotland.Do I have right to any money from the home(is it our matrimonial home),as I lived there,and spent money for upkeep?
