In short
Marital Affair is a discreet dating site for married and attached adults, and this is its local guide for Chicago. Joining and browsing are free; messaging is paid, in US dollars. Illinois still has an adultery offence for open and notorious conduct, but divorce is no-fault. The Chicago Department of Public Health treats STIs regardless of ability to pay.

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 lists the options. Prices are in US dollars. Checkout shows the billing name that will appear on your card statement, and memberships renew until you cancel in Settings > Billing. You must be 18 or over to join. Because profiles are shared with partner sites in the same network, some people you hear from will have joined through another site.
The law in Illinois
Illinois is one of the states that still has an adultery offence. Section 11-35 of the Criminal Code (720 ILCS 5/11-35) makes it a Class A misdemeanour where the conduct is "open and notorious", for a married person with someone who isn't their spouse, or an unmarried person with someone they know is married.
Divorce is a separate matter, and fault plays no part in it. Under 750 ILCS 5/401 the only ground is irreconcilable differences that have caused the irretrievable breakdown of the marriage. If the spouses have lived separate and apart for a continuous six months before the judgment, the law presumes that requirement is met, and it can't be argued otherwise. This isn't legal advice; speak to a family lawyer before acting.
Sexual health in Chicago
The Chicago Department of Public Health runs three Specialty Clinics for STI and HIV testing and treatment, including gonorrhoea, chlamydia and syphilis, plus PrEP and mpox vaccines:
| Clinic | Address | Phone |
|---|---|---|
| Lakeview North Clark Street | 2849 N. Clark St., 1st floor | 312-744-5507 |
| Austin West Division Street | 4909 W. Division St., Suite 411 | 312-746-4871 |
| Roseland East 115th Street | 200 E. 115th St. | 312-747-1090 |
CDPH says it provides care regardless of your ability to pay or whether you have insurance. Appointments are preferred, and each clinic may take walk-ins on a limited schedule, so call first. Lakeview is open five days a week; the clinics close for lunch between noon and 1pm.
The CDC's GetTested finder at gettested.cdc.gov lists other free and low-cost testing near you, and our guide to sexual health with a new partner covers what to test for and when.
If someone tries to scam or threaten you
- The FTC, at ReportFraud.ftc.gov, for romance scams and other fraud.
- The FBI's Internet Crime Complaint Center, at ic3.gov, for online fraud and sextortion.
- 911 if you are in danger or a crime is happening now.
- StopNCII.org if someone threatens to share intimate images: it lets an adult create a digital fingerprint of an image on their own device so participating platforms can find and remove copies.
Don't send money or more photos. Keep the messages and report the profile through our help centre. The guide to scams and blackmail explains how these schemes usually run.
Talking to someone
If you want to talk it through, a licensed marriage and family therapist will see individuals as well as couples. If you are struggling, call or text 988, the Suicide and Crisis Lifeline, at any time. Our page on getting support lists more places to turn.
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.

Where can I get tested in Chicago?
The Chicago Department of Public Health runs STI clinics at Lakeview (2849 N. Clark St.), Austin (4909 W. Division St.) and Roseland (200 E. 115th St.), offering testing and treatment for gonorrhoea, chlamydia and syphilis, HIV testing and PrEP.

Is adultery illegal in Illinois?
On paper, in some cases. Section 11-35 of the Illinois Criminal Code makes adultery a Class A misdemeanour where the conduct is open and notorious. It isn't a ground for divorce: since 2016 Illinois divorces rest on irreconcilable differences alone.
Where do I report a romance scam?
To the FTC at ReportFraud.ftc.gov, and to the FBI's Internet Crime Complaint Center at ic3.gov for online fraud or sextortion. Call 911 if you are in danger, and contact your bank straight away if money has gone.
