I'm in a fairly new relationship with somebody quite a lot older than me (by 20 years). I love him, I think he's great, he treats me fantastically but there's one thing I'm finding so hard: he has a 12 year old daughter. She doesn't live with him, in fact she lives in a different country, however I can't help but feel jealous every time he speaks to her on the phone, goes to visit her, even mentions her etc etc. I feel awful for thinking it, but I wish he didn't have a child. I don't want to have to share his love and affection. I don't want him to love her more than he loves me. I feel absolutely pathetic for feeling this way, but just I can't help it.
Whilst it's still early days, we have spoken about having our own children. I never used to want them but recently changed my mind and know that I do, however I can't help but feel sad that he's already been there, done that.
How can I get over my feelings and move forward? I try and convince myself that it's fine and it's good that he's a good dad, however the majority of the time it upsets me. I'm scared it's going to ruin our relationship further down the line and cause resentment, however I do love him and would love to be with him for a really long time. I'm just scared that the jealousy will eat away at me, so I really want to get over it. It's strange because I've never really been a jealous person up until now.
I already know that I'm ridiculous (and perhaps immature) for feeling like this, but I'm just looking for some constructive advice please. Has anybody ever been in this situation and how did you move on?
Thank you.
