This situation might tear us apart

My boyfriend and I had sex like three weeks ago. (June 1) We did it on the day we were going to see each other for the last time until July 17 because we have other plans for the summer. So we are separated right now. It was both our first times.

After he left I began getting worried that I could be pregnant even if we used a condom. Just yesterday I was honest with him and told him that I was scared that I could be, because I was experiencing weird symptoms. Later that day he was acting weird so I asked him if he wanted a break. He said he thought that would be a good idea because right now our emotions are through the roof and we aren’t together so it’s really hard. We agreed that sex right now isn’t right for us and we aren’t ready yet. He told me to Snapchat him everyday so that he can know what I’m up to. He will do the same. He wants to still be aware of what’s going on in my life. We just aren’t going to text or talk for like a month. He told me to text him when I got me period though. And I got my period this morning hooray! I texted him but he’s been busy so he hasn’t seen it yet.

The point of this whole thing is....I’m worried that this whole “break” might actually drive us apart, and maybe he will feel that he might enjoy life more if I’m not in it. He told me he has a sour taste about us right now and he wants a restart since we’ve had a rocky month. I understand though. He told me that I’m the only girl he adores and that I’m everything he’s ever wanted. He said he still loves me so much. I should be happy, but I’m worried that he will change his mind after this month. Could a break actually help us? Or is he doing this to eventually initiate a break up? I just want to know what others think and possibly give me some advice...
