To marry, or not to marry

[user1488751927]

I have a past of DV with a previous partner, so perhaps that is making me ultra cautious/scared.

I am currently 19 weeks pregnant, and my partner (baby's father) wants to marry.

I often read on MN that a woman would be a fool not to marry if she is pregnant. However I have my reservations:

If I marry, I will lose my social housing (he lives in a bigger house and won't move into mine because his privately rented place is bigger), and I will lose my child tax credits - thus making me more dependent on him. I'm a student with just a scholarship.

Can someone explain why marriage is touted as the safest option?

*shouldn't feel the need, sorry

I think you're being understandably cautious and rightly so. Don't rush into marrying him for now-
If he's a good egg he'll understand.

If you are staying in his place all the time and contributing you are running joint household.
Why would he not move in with you?
How much bigger is the flat he rents vs one you have?
