Receiving multiple unwanted text messages can be frustrating. Whether you have an admirer who is interested in you or an ex-friend who won't let an argument go, you're probably running out of patience. Let the person who's texting you know that you want them to stop contacting you. Remain calm and kind so that you don't create an awkward situation for yourself.
Tell the person to stop contacting you. You can text them to let them know, but if you call them or speak with them face-to-face, your point will get across more firmly. Remember, being kind doesn't mean you have to be a pushover. You can stay respectful while setting boundaries. Plus, if you're not clear enough, the person may not get the message completely. Leaving room for interpretation will only leave room for the text messaging to continue.
Consult your boss at work or a teacher at your school, if the person who's texting you is from either of these places. Your job or your educational setting may have guidelines set up to deal with harassment. If the texting continues after you ask the person to stop, a supervisor or teacher may ask the person to stop as well.
Stop all contact with the person if the text messaging continues. Sometimes even a negative reaction, like asking the person to stop contacting you, is enough for the person to continue -- they may want some response from you regardless of what that response is.
Change your phone number. Make sure to only give your new phone number out to a select group of people, like your family members and close circle of friends. You may have to advise everyone to not pass along your number to anyone else. Also, you can make your number blocked so that it won't show up on caller ID when you place a call.
Contact the police if the person continues to contact you after you've clarified that you want them to stop. This is particularly important if you start to feel threatened by the person. If the harassment extends beyond text messaging, such as constantly calling or showing up at your home or place of work, contact authorities immediately.
If you start to lose your patience, remember that this may be someone who you'll have to see on a regular basis. While you want to clarify your expectations, you don't want to create an uncomfortable situation for yourself and the people around you.
