There’s a big difference between “not doing everything right” and hurting other people — especially children. You’re making a big mess and you need to stop acting irresponsibly.
First of all, by dating a married father of one while his wife is pregnant, you’re hurting:
1. His daughter.
2. His son who will be born shortly.
3. His pregnant wife.
4. Your fiance.
5. Yourself.
In that order. While this guy may be making out with you and dating you, it’s extremely doubtful he will leave his wife for you. If he really wanted to leave her, he’d be divorced already. More likely, he’s interested in having sex with a 19 year old young woman, while his wife is pregnant, uncomfortable, and busy being a mother, and since you’re ready and willing, you’ve become his Ms. Right Now — on the side. 😳 He’s not a good guy, but what’s of more concern is your choice in this man.
Since you don’t seem that interested in your fiance of one year, who you’ve been dating for four years, the best thing to do is break up with him. You’re already cheating on him, and this is no way to be in an engagement, let alone start a marriage. You owe it to him to move on since you’re looking for freedom.
Once you do move on, date like crazy — but date men who aren’t going to hurt you and who’s families you are not going to hurt. There’s nothing wrong with breaking up with someone, to date around, but just do it in the right order.
