So sorry to hear this, good advice from everyone here. Keep your dignity, and start reading:
Relationship Breakdown and Divorce ? Advice and Links
It is useful if you can get to grips with the language of family law and procedure, and get an understanding of your rights, BEFORE you see a solicitor. If you are well prepared you will save time and money.
Children
If there are children involved, their welfare, needs and interests are paramount. Parents have responsibilities, not rights, in this regard. Shared residence means both parties having an equal interest in the upbringing of the children. It does not mean equal (50/50) parenting time - children are not possessions to be ?fairly? divided between separating parents.
A divorce will not be granted where children are involved unless there are agreed arrangements for finance, and care of the children (?Statement of Arrangements for Children?). It is obviously quicker and cheaper if this can be agreed but if there is no agreement, the Court will make an Order - ?Residence and Contact? regarding children, ?Financial Order? or ?Ancillary Relief? in the case of Finance. Information and links to these can be found in the Directgov link below. Residence and Contact Orders are likely to be renamed Child Arrangements Orders in future.
Always see a specialist family lawyer!
Get word of mouth recommendations for family lawyers in your area if possible. If you have children at school, ask mums you are friendly with if they know of anyone who can make a recommendation in your area. These days there are few people who don?t know of anyone who has been through a divorce or separation ? there?s a lot of knowledge and support out there!
Many family lawyers will offer the first half hour consultation free. Make use of this. Don?t just stick with the first lawyer you find ? shop around and find someone you feel comfortable with. You may be in for a long haul, so it helps if you can find a solicitor you?re happy with.
If you can?t find any local recommendations, always see a solicitor who specialises in Family Law.

Some family law solicitors publish online feedback from clients ? Google solicitors to see if you can find any recommendations or feedback.
Mediation
You will be encouraged to attend mediation. This can help by encouraging discussion about arrangements for children and finance in a structured way in a neutral setting. However, it only works if both parties are willing to reach agreement.
If there has been violence or emotional abuse, discuss this with your solicitor first. Always get legal advice, or at the very least make sure you are aware of your legal rights, before you begin mediation. This is important because while a Mediator should have knowledge of family law, and will often explain family law, they are not there to give tailored legal advice to either party - so it?s important to have that first.
Married or Living Together?
This is a key question, because if you are married, generally speaking you have greater protection when a relationship breaks down.
Legal Issues around marriage/cohabitation and relationship breakdown are explained here:

Finance
Before you see a family law solicitor, get hold of every single piece of financial information you have access to, and take copies or make notes. Wage slips, P60s, tax returns, employment contracts, pensions and other statements ? savings, current account and mortgages, deeds, rental leases, utility bills, council tax bills, credit statements. Are there joint assets such as a home, pensions, savings, shares?
If you have no access to financial information, or you are aware that assets are being hidden from you, then obviously you will not be able to reach agreement on finances. If there are children, as you cannot divorce without adequate arrangements being agreed on finance and children, you will have to apply for a financial order anyway. If there are no children, and you are unable to agree on finances, you will also have to apply for a financial order (follow the Direct.gov links below). This seeks financial information from both parties going back 12 months. So it is in your interests to act quickly once you have made the decision to divorce.
If you are married, the main considerations of the Family Courts where parties are unable to agree a settlement are (in no particular order of priority):
1.The welfare of any minor children from the marriage.
2.The value of jointly and individually owned property and other assets and the financial needs, obligation and responsibilities of each party.
3.Any debts or liabilities of the parties.
4.Pension arrangements for each of the parties, including future pension values and any value to each of the parties of any benefit they may lose as a result of the divorce.
5.The earnings and earning potential of each of the parties.
6.Standard of living enjoyed during the marriage.
7.The age of the parties and duration of the marriage.
8.Any physical or mental disability of either of the parties.
9.Contributions that each party may have made to the marriage, either financially or by looking after the house and/or caring for the family.

I think you retain far more dignity by letting the little shit run along than you ever would confronting his new girlfriend.
