I need advice please!

So i have been with my boyfriend for nearly 3 years and he only wants to know me when it suits him. We have a baby together, before i was pregnant he would alwahs be with me ect. Now he only stays round mine once a week, if that. Im always the one asking him if he wants to stay over, he never actually makes the effort to ask or say he is or anything like that.. its always me asking him!

I asked him today if he wants to stay round the whole weekend and his reply was "i will let you know" .. why do i even bother ?!?!!

I dont feel good enough at all
