Am I crazy jealous?

I've been with my boyfriend about two months now, and he is absolutely perfect couldn't wish for anything more. However before he was with me he was in a relationship for about 2 and a half years. His ex lied and cheated on him with various men, and then she fell pregnant, told him she had never cheated and that the child was his. They moved in together, he was there throughout everything, the child was born, but he had suspicions..did a dna test and discovered the child wasn't his. So they split and this was about a year ago. The house they rented was under his name so he is still in contact with her, understandably as he has sort any maintenance issues with the landlord. However i really do not feel comfortable with him being in contact with her. He says he is only in contact with her to discuss any legal/housing issues...but i discovered not to his knowledge that recently he met her. No idea why, i can't really ask...although i trust him 100% and i know nothing went on. What i can't understand is why he would still want to see her? I don't want him to have contact with her once this housing contract has ended...am i being controlling? I don't want her in his life full stop, and i feel that strongly about it i don't think i could be with him if he said he would have to be, no compromises. I feel like i can't move past this, also about a year and a half ago i fell pregnant myself, however my boyfriend at the time controlled and destroyed my life. He forced me to terminate my pregnancy, and i feel incredibly jealous of my current parters ex..maybe because she has something i could have had. It makes it harder when i have always been told i will never be able to have children. I am aware that i have low self-esteem or low-confidence...not that you would ever know it as anyone who knows me sees me as incredibly confident people person. I am self-conscious about my weight, I'm about a size 14...and the fact that my boyfriend's ex is a size 8 does bother me. Really don't know what to do, i don't know if i am being irrational if i ask him to stop contact with her, but i won't be able to cope if he does. Someone please help?

Hey relax there! Your boy friend will not go back to his ex. Not after all that he has undergone with her. He is with you for a stronger reason. She can't get past that to him. See they have shared a life together and it is possible they might have had some issue to discuss and settle? If he does not do it often I don't think you need to worry. Let him come out and share with you when he meets her. When you act crazy around that you will encourage him to keep such issues private away from you. And Life is strange, there is a God above all the docs in this world. It is he who decides if its time to have a child or not. Just have trust in him.

Shivangi, thankyou for your reassuring words. It encouraged me to speak to my partner calmly and discuss the issue. There now are no issues, and everything is back to being perfect between us. He was incredibly understanding. But in relation to the other two responses..this is actually hilarious. I never stated i was living with him, nor is the child his, nor is he still with his ex. To inform you all, he has no feeling left for her, and is happy to remove her from his life once the legal matters are sorted. And do you know what? I may not have been able to deal with my own issues and grievance in the way i liked. Can i also point out i did not have a choice in my pregnancy. So by the way, my partner is over his ex. Yes, i have made poor choices, but i have learnt from them. I am strong enough to stand back and let him close the doors on his past. Oh, and if i wanted abuse about my relationship..i would have posted it on Facebook. I am happy. And thank you for those unhelpful comments. They made me realise, i am stronger than i thought. I do not need to monitor my partners every move, because i trust him 100%...and its clearly over? Definitely the last time I even consider listen to people's negative views, thanks guys!
