So me and my ex have been together 3 years and we were both very unhappy. We are now planning to split - I’m staying in rented property and he is helping me out with guarantor so I can stay. He is moving back to house share (as close as he can) so if needed he can support me and our child. We are suddenly getting on so well. I’m 100% sure I want us to split and live separate to realise what we both want. Now - It’s almost upsetting how nice he is with the whole thing and how great we are and I’m wondering if we will both regret splitting up ? He is also trying to have sex with me now but I’m refusing but secretly scared he will go find someone else / I’m still secretly hoping there is hope for us down the line. What do you think about this whole situation 
. Anyone experience something similar? Issues for splitting us is basically his lack of interest in family time and time with me/broken trust after finding naked pic of a woman on his phone and him lying about few things.
