Hello! This is my first post on here, looking for some advice on a situation.
My partner of two years has 3 children, all boys. A 12- & 10-year-old from a teenage relationship, and a 3-year-old from a marriage.
I am very actively involved in the 12- & 10-year-olds lives and their mother and her side of their family really respect me and the role I play. Over the past two years I have got both boys involved in sport, including picking them up a couple of times a week while my partner has been working to take them, making sure they're including in holidays abroad, taking them to hospital appointments when needed, and most recently the 10 year old has expressed interest in going to grammar school (his mum is on job seekers and wouldn't be able to afford it) so I said I'd be more than happy to pay half with my partner and this is something he really wants to do.
Overall, I have a really good relationship with both boys and love them with all my heart.
My partner also has a 3-year-old who I have never met and doesn't know anything about me. To some context to this, his mother is Latvian and after their marriage ended, she took him to Latvia and has been a bit difficult about everything since.
The marriage wasn't a happy one to say the least, and as a result my partner attempted suicide on multiple occasions. The boys hated and still hate her, she made it very clear she didn't like them, to the extremes she refused to do their washing as the boys in her eyes weren't anything to do with her.
Now this is where it starts to get a bit more complicated. My partners ex-wife refused to let me see their son when she was still living in our town because she was jealous that my partner had moved on and she'd lost control and made every excuse in the book as to why I couldn't see him. When she left the country, the arrangement was he'd spend a week in England and my partner would spend a week in Latvia every year, and that they'd video call every Sunday. For the past year I've been sent out of the room when his son calls, including on boxing day when the whole expended family was round, the boys at times have become very upset over it. Every time my partner has mentioned him coming to stay here, she says no because of me.
The situation which has really upset me today is she has texted to say she'll be coming here for a few days and my partner can have him. I haven't said anything back because I am dreading being told I'm not allowed to meet him. After everything I feel I've done for the other boys I think this will truly break my heart.
P.S. a bit of background about me, I'm a professional, who is a Director of Marketing and a School Govenor.
Apologies for the long post but I'm so upset I don't know how to respond. Thank you.
