So he is your partner for those that say it is not mentioned. I believe if a person lives with you for a certain amount of time they then have certain rights but it all depends on your situation with your partner. It has become known that a partner living together with the owner of the property has taken it to court and actually won even though they had no rights. So it is something you need to be careful of even if you finish with your partner.
I live with my partner and from the beginning I made it so that rent was paid every month so that way I was not being taken for a ride. So far after several years it has worked out OK and rent has always been paid. I keep a rent book which I believe can act as a legal thing if taken to court, but not 100% sure of this.
Owner occupiers who live together
Your home may be owned by just one of you, or you may own it jointly.
If your partner is the sole owner, you may have no rights to stay in the home if your partner asks you to leave. However, if you have children, you can ask the court to transfer the property into your name. The court will only do this if it decides it is in the best interests of your children. If you don't have children, you may be able to claim a beneficial interest in your home if you can show you contributed financially by, for example, paying for improvements or towards mortgage repayments. If you do have a beneficial interest in the home, you might be able to stop the other person from selling it. You will need to get legal advice about whether or not you have a beneficial interest.
If your relationship ends and there are children involved, the court has the power to order a transfer of the property as part of an overall settlement in order to secure accommodation for the children. This is usually done for a limited period, for example, until the younger child is 18 years old.
If your relationship has broken down, you should get advice from a legal adviser who specialises in the breakdown of relationships.

Depends how difficult this gets you will inevitably need a solicitor or CAB help if he finds he has a claim to your property.
Good Luck its never easy. Having been bitten more than once myself but did get things sorted amicably in the end. Its always best to talk to your partner first and don't threaten with any kind of court proceedings as it may antagonise until you have exhausted all avenues. Be calm and sit down and talk even if it means getting a close friend of both of yours to mediate.
