pregnant and dumped

part 4~What do I do now?

It's Saturday 17th July and Molly has got to start babysitting Jacks brother again.  She has to be there at 5pm and she leaves at about 8pm. Molly still sees Jack alot, at school and usually after school at his house on a Friday.
(BTW I didn't know if you knew but Molly and Jack are still dating since 'the situation')
It's 4:30pm so Molly starts to get ready to go to Jacks so she can look after his little brother 'Ben' (Ben is 4years old).
At 4:55pm she leaves to go to Jacks.
When she gets there she knocks on the door. 'Stacey' (Jacks mum) answers the door. She lets Molly in. Jack goes to football practice at 4pm so Molly walks in ready to get Bens dinner like she usually does and then let him play and at 6pm give him his bath and then at 7pm read him a bedtime story to sleep. But no. Instead she sees Jack lying on the sofa with 500 boxes of tissues around him, 450,000 dirty tissues around him, a sick bowl  and the TV on.....the football channel.
"What's wrong with Jack?" Asked Molly.
"He has a really bad sick bug. Your mum said you had it. Are you better now?" Said Stacey.
"Oh okay. And uhm yeah," said Molly.
~~~
Stacey leaves for work and then it's just Molly, Jack and Ben. It's 7:30pm so Ben is in bed so it's just Molly and Jack. 
*Should I just tell him, or wait?* Molly thinks to herself.
"What's wrong with you? You're in a different world. You got something on your mind? You know you can tell me," said Jack.
"Uhm.....*there is silence for a few seconds* well....," said Molly.
"What is it? Spit it out," said Jack huffing.
"I might be pregnant....." spluttered out Molly.
There was another minute of silence.
"Uhm...oh okay then....it isnt mi-" said Jack.
"Yes it is. I haven't had sex with anyone else," said Molly really quickly.
Jack glared at Molly.
"What do you expect me to say?" Said Jack, evil like.
"I don't know. I thought you would have some sympathy or something," said Molly.
"What! Sympathy! You're the one who jumped into bed with me!" Shouted Jack.
"Shh, you're gonna wake your brother up. And actually I didn't jump into bed with you, you basically forced me," Said Molly in a quiet tone.
"You stupid slutty, fucking whore," said Jack. "you may as well have slag or slut written across your forehead, or maybe both because you are both. And don't say I forced you because you could've say no! Said Jack angrily.
Molly started to get tears in her eyes.
*how could someone be so rude* Molly thought to herself.
The front door opened.
"Hey  guys I'm back. Miss me?" Stacey said laughing.
"Yes aha, we always do," Jack said staring and glaring at molly.
Molly looked away wiping the tears away.
"Are you okay molly?" Asked Stacey concerned.
"Yeah I'm fine it's just..." Molly stopped to think of something to say. "I got shampoo in my eyes when I bathed Ben. That's all. It's okay aha,"
