Need advice 😭😭

Well where do I start 😭 my period is late so I took a test and I’m pregnant, but it’s not as simple as that..

I have two kids already. Me and my boyfriend split up about three days ago, we were together about a year and a half. The reason we broke up was because I had a feeling about something and I questioned him about it. I asked him if he felt awkward about me having kids because he said that at the very start when I first met him.. yes I know I shouldn’t of even bothered with him and I know that but I thought it was just when you tell someone you have kids already can be quite scary anyway 😔 but anyway he said it did bother him and he felt like he couldn’t get use to them and that it was something he thought about a lot.. I don’t know why he didn’t tell me. He was such a nice person, never nasty or anything but when he said that I said I couldn’t be with him, because how could I be with someone who is thinking he can never accept my kids? Anyway he’s been sending me snapchats and having normal conversations with me.. I told him today to just leave me alone because he was acting like everything is fine and like we were never together 😔 he says he loves me and that he misses talking to me. I told him it hurts to talk to him and I’m annoyed about it all. I don’t get why he even got with me if he felt like he could never get over the fact I have kids.. he’s 29 by the way so he’s not just a young lad. Anyway I haven’t told anyone I’m pregnant. For a start I pretty much have one friend and second I have no idea what I’m supposed to do. The test came up with a strong positive straight away. I am on the pill but missed one or two as my son went to hospital for an op and I was stressed and forgot 😭 I don’t know what to do!? Do I say anything to him? Do I just go to the doctors and speak about a termination!? I don’t even know anymore 😭 please no nasty comments as I’m in tears anyway😢 I’m so lost and feel so alone at the moment 😔😔

Edit. We didn’t live together or anything he would stay over like once to twice a week so he didn’t get involved in the kids lives or anything before anyone asks.
