We go through this too in our head. Me or rather the adult half of the original would love a family more than anything. The longing hurts a lot. Just recently it started to bother me again because of a resurgence in romantic feelings for my inner mate. We both know that we can never truly be together in a tangible way which really sucks but, she is willing to step aside if I ever find a mate in the outer world and just stay on as an advisor/protector/friend but, I'm working on a solution that will ultimately end for her to be happy too should I ever find a "real" mate. Sounds so cruel to say it that way as if she doesn't really exist but,... It is what it is.
She's real enough for me and I know that she feels because I can feel when she is stressed or worried about me.
So, there's that and then there is "G" who is easy going, laid back and cool. Real calm sort but, a clown too.
He just wants to do his job which is to protect us or anyone else who may need protecting for that matter. He'd like for me to give him own fiction series because he's bored but, that's still a ways off.
There are three others that are troublesome who have their own desires but, I had to put that on the back burner because I have to much on my plate already lately.
Then of course there is "DH" who is more or less a super villain with a lust for power. Keeping him in line has been kind of tough lately and it takes more than just me to control him. His desire is world domination.
A little over a month ago a new one showed up due to all of the stress that we're under. He's basically a pessimist, doesn't trust God and is very angry about many things like one for instance being that our life sucks, always has sucked and will no doubt continue to suck until the day of mercy when we are finally aloud to check out of this @#%!hole. Sorry about that.
There may be another new one but, I'm not certain of it yet. Something strange happened last night before I went to sleep and I don't know where it came from but, I sure didn't like it.
There is also the child original who would also like to know where his father is and basically me and some of the others have managed to comfort him by telling him that we are his father now. He's usually fine as long as we keep him out of harm's way and buy him things that he likes. I try not to spoil him too much but, I love him and just want him to be happy. There are other nameless ones who come and go but, thankfully they don't stick around for long or cause too much trouble so, that part isn't all that bad.
So, yeah. There's pretty much four of us in here who want a family but, it's mainly me wanting a family with the other three just wanting me to be happy.
So, I can sympathize with how you all must feel. Being a multiple is like being a messed up, jumbled mess sometimes. It's just not fair. And say someone did want to be with us? What sort of compassionate and understanding person would have what it takes to put up with us? I know that some have found mates but, what about those of us who feel like we can't for whatever reason? What do we do? Just try to forget about it and be content with what we do have? That isn't enough for me, for us. We need to express deep, meaningful love toward someone who will love us back with equal intensity. *Everyone* needs that. Is there really someone for everyone or is that just a lie to give us false hope? If you stay hopeful and try to fight against your condition with proper treatment then maybe, just maybe there will be a way out but, I'm too tired. I don't want to fight any more. But, I don't want to give up either. I want to believe in a better tomorrow for anyone and everyone but, lately it just takes too much out of me. I guess that's why I'm on this forum. I just need to express myself and try to help others when I can *if* I can and try to find some peace of mind.
I hope that you do get the family that you want and soon. I hope that you find happiness and contentment.
