@Frenchy123,
At no point in your post did you say whether either you or your boyfriend want to have children.
Okay, moving forward from there...have children because you truly want them. You want to share the love you have with a person or persons who you plan to raise, put on a good path for life and for
them to be happy and successful in all their endeavors.
Do not have a child just so you won't be alone when you get old. There are no guarantees. Any offspring might choose to live in a country other than where you are. They may decide they want nothing to do with you. It would not necessarily be a reflection upon you, they might reach that choice for any number of reasons.
If you are not sure about having a child at this time, consider having your eggs frozen.
Think about everything carefully.
If being alone is your driving force, then get involved with community activities. Make some new friends, some who might be friends for life.
