How do I confront my cousin about her bad choices?

I do have a cousin named Laura. But I don't like what she is doing to herself. Me and my family wants to have back in church. But she won't do it. I know she has her own life. Because of work and her friends and dating. But what I am saying my family and I don't like the friends that she is with. She has a friend that lives with a boyfriend that we all don't like that at all. But her friends decide for her to meet with a guy named Jeff. We hardly know him. But Laura is going out with him. I don't like that either. I don't want to see her hurt in the line of it. She wanted to go to his house but her mother didn't want her to. But Laura won't expect that anyways. Which we all found out that this Jeff guy is only 34 years. old. My cousin Laura is 18 years. old. But we all don't like that. If she wants to really be with someone I would consider on dating someone about around her age or if the guy was 22 , something like that. Because this Jeff guy has kids. Which Laura has no idea if he is still married or not. Which that is not good. What can we do about that.? It is hurting me and my family. But my dad said not to repeat to much. I can't stand that when I will be hearing it anyways. Because I know I am in this family. Whatever I hear I will always hear it. It always be talk about it in my family. What am I suspose to do when I know I am going to hear it all the time? But what I am going to do about my cousin doing this anyways. What she is going to do for the rest of her life when she doesn't respect her own parents? This is going way to far. Really do need help on this real fast and now. How do I talk to my cousin Laura about to where she won't end up hurt?

You need to sit her down and open her eyes! give her a reality check. Tell her that this guy is almost twice her age and has kids and is most probably married looking for a young naive hot 18 year old to spice up his life! she is only going to get hurt and is hurting her family in the meantime. Talk to her seriously, dont make her feel stupid becos she will become defensive and wont listen to you, just talk to her about your concerns and make her realise she can have her own like and her own friends and so on, but to take care of herself also.

Dear ahestand,
First you are not responsible for your cousin...You should not be taking this responsibility on your shoulders. This is her issue with her parents. When we see or hear about trouble in our families sometimes we tend to cross the boarder lines as to who should is the parent. You aren't so step back and if your cousin chooses to ask for your advice then sit and talk with her. If you interfere you may loose your cousin all together and I can tell you care for her and wouldn't want to loose her friendship. Let the adults handle these adult situations. Since this is what they choose to talk about all the time you can leave the room. Remember you are not her mother so don't act like it.
Sue...good luck

Yeah, I agress with Sue90, she's your COUSIN, not your sister, not your mother, not even your best friend, you COUSIN. And you know what else she is? She's 18 years old, and you know what that means? She's legally an adult and should be old enough and mature enought to make her own decisions. I'm not saying that you should just leave her in the dust, because I do understand your concern, but enough is enough. If you're on her back 24/7, that'll likely just backfire in your face, by making her angrier and more likely to rebel. This whole thing with the 34 year old man with children probably shouldn't be, but that's her decision, not yours. I'm sure it won't work out with him anyway. The fact that you don't want your cousin to get hurt is sweet, but if nobody got hurt, we'd never learn to love. Sometimes you need to get hurt to learn valuable lessons in life, she'll get over it anyway. Sure, it's a really weird situation, but it's not a threat to her life, so you and the rest of your family need to butt out ( no offense). If there's one thing people hate, it's always having others breathing down their necks and telling them what to do, the best thing to do it stay out of it. The bottom line is that you should be there for loved ones when they want you to be, not when they don't. If you really needs your help ( which she probably will eventually), she'll come to you. Howvever, if all you do is nag her, she'll probably ignore you as much as possible and won't even want you there when she need it. Good luck, peace!
