Growing resentment over partners behavior

[OneLivelyGoose]

Ik currently 38 weeks pregnant with my bfs baby. When we first started dating we were out on a date and I saw him looking at these beautiful women that walked into the same venue, I'm talking double takes. I brought this up later to him and he denied it and I know what I saw but his denial really made me second guess my own two eyes.(I did bring it up a week or two after it happened as it was nagging at me and this was after I found out I was pregnant)- and yes, I fell pregnant pretty fast into our relationship(6months in to be exact😭)

Fast forward to 30something weeks pregnant and he's driving and another beautiful girl walks past and I see him do a double take, I just make note of it. Lastly we're chilling at my house and a housemate of mine walks past us and his gaze is fixated on her as she walks past- I bring this up to him however I phrase it as though it was my friends partner doing it instead of him to which he responds it's a crazy situation and very disrespectful to her I then tell him he has actually done it to me and then again comes the denial.

I dont know what to do cause I know he is and has done this on multiple occasions but he keeps on denying it. I'm 21 and still at uni(in my final year) but I'm meant to be moving in with him in a week and there's just this growing resentment that I can't even communicate to him about as he will deny his behavior and I don't know what to do

He isn’t going to change.
Don’t move in with him and give baby your surname.

Also, be selective about who you choose to be the father of your next child.

He’s a bloke in his early 20s. It’s not unusual for him to be attracted to women and look at them. Causing upset and drama because you have noticed him look at other women isn’t going to make him grow up any quicker.

That the two of you have created a child so early into your relationship doesn’t mean that he is automatically going to become ideal partner/father material overnight.

I understand there is little room for change and unfortunately Ive already signed the tenancy. Other than this he is a great partner overall and has really stepped up into the role of being a father. Don't take this as me seeking out advice and completely ignoring it as I will definitely not be giving the baby his last name and while this living situation is best for me financially I will be saving up for my own place. The reason I asked this is because this behavior seems so weird in comparison to how he is and with how adamant he is in his denial about it, it is really confusing me

I'm already in the process of signing the tenancy but our baby will not be having his last name

Are you very young? Babies name won't make any difference, he'll still have parental responsibility and be able to make decisions about schooling, medical care, where the child lives, whether or not you take them on holiday, or request 50/50 should the relationship not work out.
Also I think it's quite natural to look at beautiful people, doesn't mean anything. I'd be aiming for financial independence in your shoes though. Never rely on a man to house/feed you.

I am 21 and receiving maternity allowance and students loan(I usually work but have been unable to to due to the pregnancy) and I'm definitely not dependant on him financially I just have signed the tenancy. and while I do agree looking at attractive people is normal, I also believe that there is a certain control you need to have about doing so especially in front of your partner, I think doing double- even triple takes in front of your partner is crazy

This.

Def do not give the baby his surname
