Help support advice?

I feel like I have been wanting to have a baby since the day I tuned 16 I am now 26 I have been in a relationship for almost 4 years with my partner having 3 children to other people 2 many years ago teenagers now that he dosent get to see and a 3rd at the beginning of our relationship which iv still never met since the mother hates me her one baby’s to Him is coming up 3 NO DNA test was ever done.

we have been trying for a baby for over 2 years now but I feel there’s something wrong with me or my partner would say it’s not the right time but we both agreed when he wanted to started trying or he’s too busy and half the time my partner is avoiding me when I’m try my hardest to satisfied him and hopefully make a baby but he never wants to. I’m lucky if we make love twice during ovulation.

So dose God hate me and decide to give me this life or is it my fault or will things change and I’ll finally be happy with a. Family, this seems to be the only place I can ask as I have no real friends and family blame my mental health having felt with depression and disappointment for not being able to conceive.

Any advice would be greatly appreciated x
