Need some thoughts/opinions/advice on where to go with some problems I have. Will try not to be too long or ramble!
Backstory - exh and I split up when I was 8 weeks pregnant due to many many issues mainly him being a compulsive liar and multiple money and attitude issues (his)
DS is 14 months now, exh has seen him every Saturday for anything between 1-3 hours depending on how long he wants to stay for that day barring occasional sickness and holidays.
Exh got a new girlfriend last summer, and it was all very up in the air about the way he told me etc.
It is worth noting that when we had a talk about the new gf the first thing he said to me was "oh don't worry she's not going to replace you as DS's mum"
Then around Christmas time, she messaged me loads of weird messages. It started off asking about DS (who as far as I know she had & has nothing to do with) then about me and exh and how she 'hoped I was happy' and that she 'hoped we would be very happy together' etc. I asked her to tell me what was going on and she wouldn't tell me and spoke to him about it and he denied all knowledge. After the denial period, he claims they were never actually together she was a random obsessed girl who wouldn't leave him alone etc
Exh has also told me he wants to take DS on holiday for a wedding this year, but there are just so many worries!! I've yet to tell him DS isn't going, but I'm slightly worried that the gf is going and it's all gonna kick off. I'm aware of the fact that his love life and relationships are nothing to do with me but I also can't get over the very first comment he made to me after I found out about her. There's so many more little bits to this too but I won't bore you with all the gory details.
Any thoughts/opinions advice???
