Dear Cheryl,

I've been with my boyfriend for five years now. I love him so much. I want to marry him. He's my first everything. However, about six months ago, I was talking online to a guy I went to school and ended up sending him a topless picture of myself.

I feel like a horrible person. My boyfriend doesn't know. I feel so guilty. What should I do? — PLEASE HELP

Dear PLEASE HELP,

Women who are in love don't flirt with other guys online, let alone send them topless pictures of themselves.

So, here's my question for you: What's missing in your relationship that you you're looking outside of it for validation and excitement?

You need to figure that out. Maybe you're too young to settle down and you feel trapped. Maybe you don't really love your boyfriend, you just feel comfortable with him.

Then you need to have a heart-to-heart with your boyfriend about your relationship. And you need tell him what you did. He's going to find out anyway, and it's better that he finds out now.

Dear Cheryl,

When I met Josh in 2012, I had overcome a rough past and felt ready to find someone to share my life. We just clicked. There wasn't anything we couldn't say to one another.

He was living with his brother and his wife at the time and I moved in, too. That's when I realized how jealous his sister-in-law was of me. It got so bad she removed our bedroom door from the hinges so we couldn't have sex!

When I became pregnant, I was treated like the devil. I was accused to poking holes in our condoms! I was told to leave. Josh decided to leave with me after I discovered he and his sister-in-law had been having an affair for over 12 years. Josh was her boy toy, baby sitter and sugar daddy and I ruined all that by getting pregnant. I'm constantly reminded of this.

We moved out, got married, had our child and have been rather happy. We don't associate with them (neither does the rest of the family), but I feel terrible that Josh no longer sees his two nephews. He practically raised them.

Things were fairly quiet for a while, but now I've started getting hateful messages on Facebook from Josh's sister-in-law and her friends. I've blocked them, but she creates new accounts. She's now sending people into my work, calling me a home wrecker and saying absurd things about my daughter. I'm pregnant again, and this has become very stressful.

We've asked for a family get-together because this has become a family problem. — WHAT SHOULD I DO?

Dear WSID?

Your sister-in-law has crossed a line, a legal line. She's harassing you. Make a list of everything she's done and contact a lawyer who will send her a cease-and-desist letter outlining the consequences if she continues.

And don't bother with a family get-together. It won't do any good. Your sister-in-law is clearly crazy and her husband doesn't seem to have any control over her. Unfortunately, your husband won't be able to have contact with his nephews until they're out of her house.

By the way, you've married into a family that sounds like a reality show. You're going to have to work very hard not to be dragged into their drama.
