Who you'll meet, and what it costs
Joining, building a profile and browsing are free; reading and replying to messages needs a paid membership, and the prices page has the options. Checkout shows the billing name before you pay. Prices have so far been shown in US dollars, so your bank converts the charge. Members in Belfast are part of Marital Affair's UK membership, and because profiles are shared with partner sites in the same network, some people you hear from will have joined elsewhere.
Sexual health in Belfast
The Belfast Health and Social Care Trust runs the city's sexual health service, with two entrances on the Royal Hospital site and a further clinic at Crumlin Road Health Centre. It works by triage, not walk-in:
- No symptoms: order a free home test kit from SH:24 (sh24.org.uk).
- Symptoms, or a positive home test: phone the GUM service on 028 9615 2111, 8.15am to 11am, Monday to Friday.
- Don't go in person unless you need PEP after a recent risk or it's an emergency.
Our guide to sexual health with a new partner explains what to test for and when.
If someone tries to scam or threaten you
- Report Fraud, at reportfraud.police.uk or on 0300 123 2040, covers Northern Ireland as well as England and Wales.
- The PSNI on 999 in an emergency, or 101 if it isn't urgent.
- The Revenge Porn Helpline supports adults across the UK. In Northern Ireland, sharing intimate images without consent is an offence under the Justice Act (Northern Ireland) 2016.
Stop replying, keep the evidence and report the profile through our help centre. See the guide to scams and blackmail.
Northern Ireland's divorce law
Adultery is not a crime in Northern Ireland, but it is still part of divorce law here. A divorce needs irretrievable breakdown, shown by adultery, unreasonable behaviour, two years' desertion, two years' separation with consent or five years' separation without it. Adultery can't be relied on if the couple lived together for more than six months in total after the spouse found out. England and Wales moved to no-fault divorce in 2022; Northern Ireland has not. The UK page compares the nations. This isn't legal advice; speak to a solicitor before acting.
Talking to someone
Relate NI offers couples and individual counselling, family mediation and sex therapy. Accord, which works across the island of Ireland, has a Belfast centre too. Samaritans are on 116 123 at any time, and our getting support page has more.
Before you meet
Our safety page and the guide to meeting safely cover first meetings, and the discretion page explains what the site shows and sends: the billing name, account emails and who can see your profile.
Questions people ask
How do I get an STI test in Belfast?
If you have no symptoms, the Belfast Trust asks you to order a free home test kit from SH:24. If you have symptoms or a positive home test, phone its GUM service on 028 9615 2111 between 8.15am and 11am, Monday to Friday. Don't turn up in person unless you need PEP or it's an emergency.
Does adultery affect a divorce in Northern Ireland?
It can. Northern Ireland still requires one of several facts to show a marriage has broken down, and adultery is one of them. It can't be relied on if the couple lived together for more than six months in total after the spouse found out.
Is having an affair a crime in Northern Ireland?
No. Adultery is not a crime anywhere in the UK. Fraud, blackmail and sharing intimate images without consent are.
