If you terminate because you really don't feel ready to have a baby and you know deep inside that you do not want to be a mother - you will probably recover fairly easily and your relationship may survive.
If you terminate because you are scared of losing your boyfriend - you may regret that for the rest of your life & your relationship is unlikely to survive unless you can truly forgive him for the situation he has put you in. He will also have to live with the guilt & responsibility of pushing you into a decision when he knows it is not what you really want. Believe me, he DOES know because you have told him more than once.
His tears are out of panic because he is scared of his life changing.
But what about you? If you are the love of his life, your health and well-being should be his priority. Instead, he is making it all about him. He is also telling you that he will support you in what 'you decide' because that means the responsibility & potential guilt are put into you.
I had an unplanned pregnancy when I was younger than you are - I was 20 but my boyfriend was 29. I was head over heels in love with him and we had just made plans to travel. My boyfriend's reaction was very similar to your partners. I also said I wanted to keep the baby (although I did keep changing my mind, I was confused). My bf never actually TOLD me to terminate but it was clear that was what he wanted. There were tears from him and he was so upset by it all. When I tried to talk about perhaps keeping the baby, there was just silence from him. At the time, I thought that losing my boyfriend would be the most painful thing I could imagine.
To cut a long story short, I had the termination. A few months later we went travelling. It wasn't that great and, to he honest, I was already falling out of love with him. I didn't respect him anymore & I often used to look at him and think "someone who loved me wouldn't have pushed me to do that". "Pushing" is that he did, although it wasn't done in an up-front way.
That summer, I saw babies everywhere I went. They all seemed to stare at me in a way that made me think "they know what I did" (completely irrational, I know!). I started to have severe panic attacks when I went out.
I ended things with the boyfriend. He took it badly and kept turning up at my workplace crying and begging me to marry him & have children with him. This went on for many months. He kept saying that the termination had been a mistake. I felt a little bit of pity towards him by then but nothing more.
Anyway, I have since met and married my DH & had 3 children. I try not to dwell on my earlier pregnancy (although I hate the fact that the termination is written in my maternity notes) apart from on the date it happened, when I allow myself a day of thinking about it. It was over ten years ago. I know I am a good mother to my existing children but there will always be a part of me that feels I had another child who I "failed" badly and that I made the wrong choice. I chose my boyfriend over my unborn child.
My ex-boyfriend had another unplanned pregnancy with his next girlfriend after me, they had been together for about one month. He told me that he was determined not to make the same mistake twice. They had the baby & he went on to marry her & they are still together & hopefully happy. He told me that he will always feel ashamed of the way he behaved.
Anyway, a long story there! I know your situation is different to mine and you must decide what is right for you. I just wanted to try & give you some perspective, as in - having a termination will not make the whole situation just 'go away' and put you and your boyfriend back to where you were.
I am pro-choice and I have several friends who chose to terminate unwanted pregnancies. For them it was absolutely the right choice and I don't think they had any long-term problems as a result of it. For me, it wasn't.
Please, think about what you want as you will carry the decision - either way - for the rest of your life. Your boyfriend may not be in your life for that much longer, as inconceivable as that may seen to you at the moment.
Good luck x
