Good afternoon everyone, please I’d like to stay anonymous. I really need your advice.
Last year in July, my elder female cousin introduced me to her husband’s cousin, and we started talking from there. We began dating towards the end of July, and honestly, things have been going well. He’s caring, responsible, and very intentional, which I truly appreciate. We’ve grown to love each other deeply.
We had plans to get married this May, but due to preparation challenges, we postponed it to October.
However, something has come up that’s really bothering me. I recently found out just today that he has a 7-year-old son, and he never told me about him throughout our entire relationship. This has really shaken me because I feel like something so important should not have been hidden, especially from someone he plans to marry.
My issue isn’t that he has a child, but the fact that he kept it from me for so long. It makes me feel like the relationship wasn’t built on complete honesty. I can’t help but wonder if he would have told me at all if our wedding hadn’t been postponed.
He says it’s not a big deal and thinks I’m overreacting, but I genuinely feel hurt and betrayed. He even admitted that his sister advised him to tell me early on, but he chose not to.
Now I’m confused about how to process this and what to do next. Should I inform my mother about this? And how do I make him understand that my feelings are valid and that this is about trust, not just the child itself?
I would really appreciate your honest advice. Thank you.

So I met this guy in my workplace and we became friends he drops me off and picks me up every morning cos we stays junction away from my house. During our relationship, onetime I went through his phone and realized he’s seeing someone she’s been sending him nǔdes and all I confronted him and he told me the girl has been sending him and all but he did not ask for them, yet n***a man saves in chat. I decided to let’s go cos he promised to block her which he did. I forgave him not only because of that but also because he met her before me and looking at their chats it’s more of save in chats than the text. Fast forward two months in the relationship I go through his phone one time when he was sleeping only to realized my man again has been receiving nüdes from this girl(another girl) who happens to be in his church and is his pastors ex . So I woke him up that dawn cried my eyes out spoke about it and this guy said half of the story I wasn’t convinced enough I took the lady’s number met her with my so called man we all sat and I was surprised my man was still fûcking her apparently he was even dating her before he met me, and she cheated on him several times so to hurt her back he broke up with her and never told her but was still having sekx with her. I was hurt cos I felt used. So on that day they both settled their issue he removed her on snap and blocked her again. But I did not want to continue the relationship again cos I’m hurt. Unfortunately we work in the same company but different department and I still love him. He’s promised to change he’s been crying and is on my neck to give him a chance. I’m so confused right now I still love him but I’m scared to commit cos I think he will hurt me again. I feel I will be hurt and honestly even when we close from work going home when I hear his iPhone I get scared cos I feel a lady has texted. Please I need your advice what do I do
