Sex with my man

When we met the sex was amazing. Now that we live together going on 3 yrs and it FUCKING Sucks! I love him and I'm okay with not having sex here and there. I don't force him. Even if it's just head that i give to please him when he asks. I'm okay with it but for the times that HE wants to get freaky i give him head for at least 20m if not more, but once we get to intercourse he finishes right away... Lately i been gaining weight but I'm only 130 (since i got the implant) which is nothing that can't be fixed but he tells me im getting fat, which to me it's just baby fat. I don't know what to say but i honestly don't think he loves me anymore. Ladies please help a mama out.

We just had a baby girl last yr on the April 14th, 2022

She's 8 months now.
