Raising a child is rewarding and hard at the same time. You will be tested physically and emotionally like you have never known, but the joys are incredible. Ultimately, you must think about what is best for your child; raising her together or offering her to a loving family through adoption.
Your problem can be someone else's blessing and you can play a big part by suggesting to your girlfriend that she explore this option. You can't force this choice, but you can look back and know that you offered leadership and long term hope to your girlfriend and your baby. Read more about adoption and find out on UnplannedGood's website about others' experiences as well as many other resources.
Your wife/girlfriend can make this choice, but before she does, talk with a trained Client Advocate so you can make an informed decision. The decision is irreversible and there are health and emotional risks involving both you and your wife/girlfriend. Someone might say, "Just have her get an abortion," and this may seem like an easy solution, but it may ultimately be the hardest road to walk.
The 'politically correct' response the world tells us we should give is: "I'll support you no matter what you decide." It takes two to make a baby and two to make a healthy decision about what to do next. We encourage couples to talk through their decision together. Both male and female Client Advocates are available to talk with you individually or as a couple so you can make an informed decision together.
Out of the relationship or out of town or whatever; just out. This seems like the easiest option, but by choosing it you will find you can never escape yourself. The decision to make it easier on yourself at the expense of others will follow you for the rest of your life.
