like they are not sure if they will spend the rest of their life with their partner. no matter how much you love them. or are good to them and they are you, that realistically you may at some point not be with them? even if you have children together? I am currently pregnant been with my partner for 2 years and I have 2 children with a previous man. I don't know if it's the hormones or what but I have just been thinking that what if it's doesn't work out what if we split one day ( my ex cheated) I chose to leave and I'm not saying my current partner would ever cheat and I feel our relationship is perfect for us but what if we split I will have 3 children and well both dad's have the freedom to just start again! just like my ex did. I Don't really know why im writing this I just feel really down about it and wondered if anyone else ever feels this way?
