Abi, if i were u, i'd look into getting a pet. if u already have one, get another : ) i suggest a small puppy. they're just as much of a responsibility and i personally think they have "human tendencies." but on another scale, if you seriously want to get rid of these thoughts that seem to be doing you more harm than good, you might want to speak to a counselor. i'm not implying that anything is wrong with you, but if you speak to a professional about this, they may be able to help you get rid of these thoughts. i'm no psychologist, but i do believe that your strong desire for a baby may have resulted from a past experience, meaning you may have underlying issues that you want to resolve, but just need help in doing so. that's nothing to be ashamed of...it's actually a good thing that you're speaking about this. it means you're acknowledging that these thoughts are negative (i say that only b/c they're causing you stress) and trying to make them positive.
Another thing you can do that might help is set up a plan with your boyfriend. maybe you guys should discuss how you see your future together..... what are ur goals? when do you think you'll be ready for marriage? what type of things do you want to experience as a couple and individually? once you two answer all of these questions, and i mean like seriously think them thru and come up with the most precise answer possible, u will then have somewhat of a plan laid out before you. this will help u to determine where having a baby might fit in. at least if you are able to give urself an estimated time that having a baby will best suit u and ur bf, you won't have to ask anymore, reducing arguments with ur bf, and plus, you'll have something to look forward to....and i don't just mean a baby, even thou it is the best thing anyone can look forward to, but whatever goals, activities, and dreams u and ur boyfriend come up with! let me kno how it turns out...plz post back if u need more advice. i hope this helps! GOOD LUCK!
